Question
A light ray enters medium 2 from medium 1. If the medium 2 has a refractive index less than medium 1, the light ray would _____ on entering medium 2.
- Bend towards the normal
- Bend away from the normal
- Not bend at all
- Bend by an angle of 45 degrees
Hint:
When medium 2 has a refractive index less than medium 1, the light ray would bend away from the normal on entering medium 2.
The correct answer is: Bend away from the normal
A light ray enters medium 2 from medium 1. If the medium 2 has a refractive index less than medium 1, the light ray would bend away on entering medium 2.
- The refraction in a pair of mediums depends on the density of the medium one and two.
- The refraction is more when the density of the medium is more.
- If the medium is rarer, the light ray will bend away from the normal.
- When the density in medium 2 is less than medium 1, the ray that enters medium 2 bend away from the normal.
