Question
A light ray traveling in kerosene (n = 1.44) enters water (n = 1.33). It bends ___ the normal.
- Towards
- Away from
- Along
- Opposite
Hint:
When light travels from a denser medium to a rarer medium, it bends away from the normal.
The correct answer is: Away from
- When light travels from a denser medium to a rarer medium, it bends away from the normal.
- Here kerosene is denser as it is having more refractive index and water is rarer so it will bend away from the Normal.
