6th Class Science 11th Lesson Shadows – Images 2 Mark Important Questions and Answers<\/h3>\n

Question 1.
\nWhat is the need of light?
\nAnswer:
\nWe need light to see objects.<\/p>\n

Question 2.
\nWhat is light of source?
\nAnswer:
\nSubstance which gives light is known as a source of light.<\/p>\n

Question 3.
\nWhen the shadows are formed?
\nAnswer:
\nShadows are formed when opaque objects obstruct the path of light.<\/p>\n

\"AP<\/p>\n

Question 4.
\nWhat we need to obtain shadow?
\nAnswer:
\nIn addition to light and object we also need a screen to obtain the shadow of an opaque object.<\/p>\n

Question 5.
\nAre you guess the colour of object by its shadow?
\nAnswer:
\nThe colour of objects cannot be determined by looking at their shadows.<\/p>\n

Question 6.
\nHow the light travels?
\nAnswer:
\nLight travels in a straight line.<\/p>\n

Question 7.
\nWhen the light reflected?
\nAnswer:
\nLight gets reflected when it falls on any object.<\/p>\n

Question 8.
\nHow do the people know that light travels in a straight line?
\nAnswer:
\nPeople came to an understanding that light travels in a straight line by observing the shapes of shadows.<\/p>\n

Question 9.
\nWhy am I not able to see the objects clearly when it gets dark?
\nAnswer:
\nIn the dark light is not sufficient to see the objects.<\/p>\n

Question 10.
\nWhy am I not able to see the objects when the power goes off?
\nAnswer:
\nWhen the power goes off light is absent. So we can\u2019t see the objects.<\/p>\n

Question 11.
\nHow are we able to see the objects in the presence of light?
\nAnswer:
\nThe light reflects eyes that fell on objects. So we are able to see the objects.<\/p>\n

\"AP<\/p>\n

Question 12.
\nWhy are we not able to see the objects in the absence of light?
\nAnswer:
\nLight is the source of visible since. So without light, we can\u2019t see anything.<\/p>\n

Question 13.
\nWhat are the conditions to form a shadow?
\nAnswer:
\nWe need a source of light and an opaque object and a screen to get a shadow.<\/p>\n

Question 14.
\nHow in ancient days, people came to an understanding that light travels in a straight line?
\nAnswer:
\nIn ancient days, by observing the shapes of shadows people came to an understanding that light travels in a straight line.<\/p>\n

6th Class Science 11th Lesson Shadows – Images 4 Mark Important Questions and Answers<\/h3>\n

Question 1.
\nHow can we see the objects?
\nAnswer:<\/p>\n

    \n
  1. When we put on the bulb, light falls on the object, bounces from the object and reaches us.<\/li>\n
  2. We can see an object only when light falls on it and bounces back to our eyes.
    \n\"AP<\/li>\n
  3. The object is visible when there is no obstruction between your eyes and the object.<\/li>\n
  4. It means light travels in straight lines.<\/li>\n<\/ol>\n

    Question 2.
    \nHow do you classify the objects according to light traveling through them?
    \nAnswer:<\/p>\n

      \n
    1. The substances like paper, plank, wood, iron, etc. don\u2019t allow light to pass through them. These objects form shadows. These are called opaque substances.<\/li>\n
    2. The substances like glass and air allow light to pass through them and hence we don\u2019t get their shadows. Such substances are called transparent substances.<\/li>\n
    3. The substances such as polyethylene cover and oily paper partially allow the light to pass through them. Their shadows are unclear. These substances.<\/li>\n<\/ol>\n

      \"AP<\/p>\n

      Question 3.
      \nWrite about shadow puppet?
      \nAnswer:<\/p>\n

        \n
      1. Shadow puppetry is one of our traditional recreational activities.<\/li>\n
      2. In this, some puppets are used to form shadows on a screen and a story is narrated with the help of these shadows.
        \n\"AP<\/li>\n
      3. By using this art old epics like Ramayana and Maha Bharat were played.<\/li>\n
      4. Now a days this old art losses its glow.<\/li>\n<\/ol>\n

        Question 4.
        \nWrite the difference between opaque and transperent substances?
        \nAnswer:
        \nOpaque: An object which does not allow light to pass through it and you are not able to see the objects behind your opaque material.
        \nTransparent: An object that allows light to pass through it and you can see the objects behind your transparent material.<\/p>\n

        Question 5.
        \nVivek said that light and object are enough to form a shadow? Are you agree with him?
        \nAnswer:
        \nNo. I can\u2019t agree with this statement. I understand that only light and an opaque object are not enough to form the shadow of an object. In addition to these, we need a screen.<\/p>\n

        Question 6.
        \nCan we guess the object by observing its shadow?
        \nAnswer:<\/p>\n

          \n
        1. Mostly we guess the object by observing its shadow.<\/li>\n
        2. But it is not always possible.<\/li>\n
        3. Sometimes the shadow may differ from the shape of the object.<\/li>\n
        4. Because of light source position and shape of the object.<\/li>\n<\/ol>\n

          Question 7.
          \nWhat is a pinhole camera?
          \nAnswer:
          \nIt is a small instrument that works on the light.
          \nWith this camera, we can observe a big object through a pinhole.
          \nOn the screen, it forms a little reverse image without a lance.
          \nThe nature of the straight-line motion of light can also be understood by this one.<\/p>\n

          Question 8.
          \nLook at a tree through the pinhole camera. What do you see?
          \nAnswer:
          \nWhen I observe the tree in the pinhole camera<\/p>\n

            \n
          1. the image is small.<\/li>\n
          2. it is inverted on the screen.<\/li>\n
          3. it is colorful.<\/li>\n
          4. and appear near to me.<\/li>\n<\/ol>\n

            \"AP<\/p>\n

            Question 9.
            \nPredict what would happen if we make two pin-holes in the camera?
            \nAnswer:<\/p>\n

              \n
            1. If we make two pin-holes in the camera I predict that images are not clear.<\/li>\n
            2. But it is a wonder that it forms two images, both are clear.<\/li>\n<\/ol>\n

              Question 10.
              \nWe see our faces in the mirror every day. Is the picture in the mirror a shadow or an image? How did you decide that?
              \nAnswer:<\/p>\n

                \n
              1. The picture in the mirror is an image.<\/li>\n
              2. We know that shadows are not colored but an image has colors that are the same as that of the object.<\/li>\n
              3. A shadow shows only the outline of the object but an image shows the complete object as it is, just like a photograph.<\/li>\n
              4. The picture in the mirror has color and shows a complete object. So its an imaged<\/li>\n<\/ol>\n

                Question 11.
                \nCan you show the difference between a shadow and an image through a drawing?
                \nAnswer:
                \nYes, we can show the difference between shadows and images through a drawing.<\/p>\n

                  \n
                1. In images, we can use color and draw the whole picture.<\/li>\n
                2. Whereas in shadows we draw only outline and fill with black.<\/li>\n<\/ol>\n

                  6th Class Science 11th Lesson Shadows – Images 8 Mark Important Questions and Answers<\/h3>\n

                  Question 1.
                  \nHow do you prove that screen is necessary to form shadow?
                  \nAnswer:
                  \nAim: To prove that screen is necessary to form shadow.
                  \nMaterials: Torch, leaf, darkroom, drawing sheet, or plank.
                  \nProcedure:<\/p>\n

                    \n
                  1. Do this activity in a dark room with a torch and a leaf.<\/li>\n
                  2. Focus the light on the leaf with a torch.<\/li>\n
                  3. Keep the distance about 30 cm between the leaf and the torch.
                    \n\"AP<\/li>\n
                  4. Now the shadow is formed in the wall.<\/li>\n
                  5. Now put the torch under the leaf at a distance of about 30cm.<\/li>\n
                  6. Now the shadow is formed on the roof.<\/li>\n
                  7. Do the same activity, in the open air (outside) at night.<\/li>\n
                  8. Now we can’t find any shadow outside.
                    \n\"AP<\/li>\n
                  9. Place a drawing sheet or a plank at a distance of 1 m. above<\/li>\n
                  10. Now we can find a shadow on the drawing sheet.<\/li>\n
                  11. It means the screen is needed to form shadows.<\/li>\n<\/ol>\n

                    Conclusion: It is proved that screen is needed to form shadows.<\/p>\n

                    Question 2.
                    \nWrite the process of making a pinhole camera? (Activity – 6)
                    \nAnswer:
                    \nAim: Making a pin-hole camera.
                    \nMaterials: A PVC pipe, about 8 cm in diameter and of length 30 cm.
                    \nA PVC pipe, about 7 cm in diameter and of length 20 cm.
                    \nOne black drawing sheet. Oil -1 ml, two rubber bands, a pin, and A4 Sheet. (If you cannot get PVC pipes, take a thick sheet of paper and roll it to form tubes. The diameter and length of the tubes should be the same as that given for the pipes.)
                    \nProcedure:<\/p>\n

                      \n
                    1. Cut a piece of black paper and put it like a cap at one end of the big pvc pipe and fix it with a rubber band as shown in the figure.
                      \n\"AP<\/li>\n
                    2. Put the white paper like a cap at one end of the thinner PVC pipe.<\/li>\n
                    3. Fix it with a rubber band, now make a hole in the middle of the black paper cap with the help of a pin.<\/li>\n
                    4. Put 2 to 3 drops of oil on the white paper cap so that it becomes translucent.<\/li>\n
                    5. Insert the thin pipe into the big pipe. Your pinhole camera is ready<\/li>\n<\/ol>\n

                      Working:<\/p>\n

                        \n
                      1. Arrange a lighted candle in front of the pinhole of the camera.
                        \n\"AP<\/li>\n
                      2. Move the thinner pipe forward and backward to get a clear picture of the candle on the screen of the thin pipe.<\/li>\n
                      3. This picture is to be observed from the back of the thin pipe.
                        \nObservation: The flame of the candle appears inverted on the screen. This is not the shadow of the candle. It is its image.<\/li>\n<\/ol>\n

                        \"AP<\/p>\n

                        Question 3.
                        \nWhy the image in the pinhole camera is inverted?
                        \nAnswer:<\/p>\n

                          \n
                        1. The light from the candle travels straight in all directions from each point of the flame of the candle.<\/li>\n
                        2. But only the light coming in some particular directions can enter into the camera through its pin-hole.
                          \n\"AP<\/li>\n
                        3. The light that comes from the point at the top of the flame goes straight towards the bottom of the screen.<\/li>\n
                        4. And the light that comes from the point at the bottom of the flame goes straight towards the top of the screen.<\/li>\n
                        5. In this way, the light coming in a particular direction from each point of the flame will be able to enter into the pin-hole.<\/li>\n
                        6. And light going in other directions is blocked by the black sheet.<\/li>\n
                        7. This leads to the formation of an inverted image.<\/li>\n
                        8. The formation of an inverted image on the screen of the pinhole camera explains that light travels in a straight line.<\/li>\n<\/ol>\n","protected":false},"excerpt":{"rendered":"
