Vedclass · Answer

(C) When a glass with black streaks is placed on the camera lens,the black streaks act as obstacles that block some of the light rays coming from the object. This reduces the total amount of light reaching the film or sensor,making the image less intense (dimmer) compared to the case where no such glass is used. However,the black streaks do not form a sharp image of stripes on the donkey; instead,they cause diffraction and scattering,resulting in a blurred image. Therefore,the photograph will not look like a clear Zebra,but rather a blurred image of a donkey with reduced intensity. Thus,option $(C)$ is correct.

$A$ man wishing to get a picture of a Zebra photographed a white donkey after fitting a glass with black streaks onto the objective of his camera.
