Question

Suppose the angle of reflection measures 40 degrees. What is the angle of incidence?
A. 40 degrees
B. 50 degrees

Answer 1

Answer:

40

Explanation:

If it is a flat mirror, the reflection and incidence are the same -- 40 degrees.

If it is anything else, more information is needed.

Answer 2

Answer:

A. 40 degrees

Explanation:

The angle of reflection is equal to the angle of incidence. So both are equal.

When the rays of light fall incident on a plane angles of incidence and reflection are equal.
