Question
A light ray traveling in kerosene enters the air. 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.
- A ray of light enters from kerosene oil to water i.e., refractive index 1.44 to 1.33 i.e. from denser to rarer medium. Hence the ray of light bends away from the normal.
