Answer
A incident ray and B is refracted ray.
Reason — As A is the incoming ray so it is the incident ray and C is the reflected ray. Ray B bends towards the normal and it is the refracted ray.

When a ray of light from air enters a denser medium, it:
- bends away from the normal
- bends towards the normal
- goes undeviated
- is reflected back
A light ray does not bend at the boundary in passing from one medium to the other medium if the angle of incidence is:
- 0°
- 45°
- 60°
- 90°
The speed of light is maximum in :
- air
- water
- glass
- diamond
The incorrect statement among the following is:
- When a ray of light gets refracted from a denser to a rarer medium, the speed of light decreases.
- The frequency of light does not change on refraction.
- The speed of light V in a medium is related to its wavelength λ and frequency f as V = fλ
- The incident ray, the refracted ray and the normal at the point of incidence all lie in one plane.
