Question

An incident ray falls on the mirror as shown in the figure. Which of the following qualify to be the corresponding reflected ray.

• A. A
• B. B
• C. C
• D. D

Answer 1

The correct option is D D

Let's draw the normal at the point of incidence and try predicting the reflected ray using the laws of reflection.

We know that since the mirror is spherical, the normal at the point of incidence will pass through the center of curvature.

Now, we have an idea of the angle of incidence. We know that the angle of incidence should be equal to the angle of reflection. Hence, the angle between the incident ray and normal should be equal to the angle between reflected ray and normal.
From the options given in the diagram, ray D seems most suitable to follow this criteria.
