Question 1.A man wants to get a picture of a zebra. He photographed a white donkey after fitting a glass with black stripes on to the lens of his camera. What photo will he get? Explain. (AS1)
Answer:• The man will get the photograph of a white donkey with less intensity. Moreover, the whole photograph will have black strips instead of only the body of the donkey.
• The black strips will block the light coming from the object. Thus, refraction will take place only where the lens is clear. Thus, providing a very hazy image.
• The photograph will look like the picture below.
