A ray of light travelling in air enters obliquely into water. Does the light ray bends towards the normal or away from the normal? Why?

 

Answer

The ray of light moves from

Air (rarer medium) to Water(denser medium)

 

We know that,

When light travels from a rarer medium to a denser medium,

Speed of light decreases and 

It bends towards the normal.

 

Hence, the ray of light would bend towards the normal when light ray will enter in water
