Question
Which of the following objects does not refract light?
- Concave lens
- Concave lens
- Glass slab
- Concave mirror
Hint:
Refraction does not take place in a mirror.
The correct answer is: Concave mirror
A concave mirror does not refract light.
- The concave and convex lenses are transparent materials which allows light rays to pass through them.
- This allows the light to get refracted.
- Since a mirror is an opaque object that reflects the light ray there won't be any refraction.
