Question

A lemon in a glass of water appears bigger than its actual size ,is due to refraction of light how can you support this statement

Answer 1

Lemon appears bigger than its actual size in water due to the phenomenon called refraction of light. Light bends when it travels from one medium to another.

In this case, light travels from air to water.

But why does light bends?

Light bends as air and water have different refractive indices. Refraction occurs at the boundary of the two mediums. After the light passes through the boundary it again continues to travel in straight line. So the direction of light is different from where the light is coming. So, it appears if the object is raised or bent. Refraction also produces magnifying effect. So the lemon appears bigger in size than it normally is

Answer 2

A lemon in glass of water is seem bigger than its actual size,it undergoes refraction
------------------
refraction if the phenomenon in which the light tends to bend when it moves from one medium to other

as the refractive index of water is more than air the light will bend away from the normal which makes the lemon looks bigger
