Answer:
Option a
Explanation:
The light that strikes this surface is referred to as the incident ray, and the light reflected is referred to as the reflected ray - as one might have guessed. Respectively, the angle with which the incident ray struck the surface is known as the " incident angle, " while the angle with which the reflected ray reflects off this surface is known as the " angle of reflection. "
_______________________________________________________
By the law of reflection, you would say that the incident angle is equal to the angle of reflection. Thus, the answer is option a.
Hope that helps!
