Light ray a moves from air to water. part of ray a is reflected at the air-water boundary. which arrow in the image is the reflected ray?

a. b
b. c
c. d
d. e

Answer : The correct option is, (a)

Explanation :

Refraction : It is a bending of light. When light going from rarer medium to denser medium then the light bends towards the normal line.

Reflection : When light ray falling on the surface then the ray coming out from the surface is reflected ray.

In reflection, the incident angle is equal to the reflected angle.

Therefore, the arrow B in the image is the reflected ray.
