Question
A light ray traveling through air enters a glass slab. It ___.
- Goes along the normal
- Bends towards the normal
- Bends away from the normal
- Goes along the interface
Hint:
Rarer to denser
The correct answer is: Bends towards the normal
- Light bends towards the normal when enters into denser medium from rarer medium.
- Therefore, when light rays travelling through air enters glass slab, they get refracted and bend towards the normal.
- So, the correct option is b.
