Yogesh and Swara were looking in a water filled vessel. They could see their images clearly in the still water. Yogesh then threw a stone in the water. Now, their images were blurred. Swara could not understand the reason for blurring of the images. Explain the reasons for the blurring of images to Swara.
Answers
This is due to refraction
Answer: Concept: Multiple Reflections
Explanation: Initially, the water was still and its surface was smooth. Thus, regular type of reflection was taking place from its surface i.e. all the light rays coming from Swara's body or Yash's body reflected in the same direction on hitting the water surface and reached our eyes. Because of this, we saw a clear image.
But when Yash threw a stone in the water, the water surface became rough due to which irregular type of reflection of light occurred on its surface i.e., all the light rays coming from Swara's body or Yash's body reflected in different directions on hitting the water surface. Thus, only some part of the reflected rays reached our eyes. Because of this, we see a blurred image.
