Open in App
Solution
The correct option is B Refraction
This happens due to a phenomenon known as refraction of light.
When the rays of light bounce off/reflect from the fish, which is in a denser medium, they fall on the interface separating the two media. This causes them to move away from the normal after refraction
The point from which the refracted rays appear to come, gives the apparent position of the fish. As the rays appears to come from a point above the fish, therefore the fish seems to be closer to the surface.
