Question

a ray of light strikes a mirror. the angle formed by the incident ray and the reflected ray measured 90 degrees. what are the measurement of the angleb of incidence and the angle of reflection. ​

Answer 1

Answer:

The normal line makes a 90 degree angle with the mirror surface. The incident ray divides this 90 degree angle into two smaller angles - the angle of incidence and the angle between the mirror surface and the incident ray. The sum of these angle measures is equal to 90 degrees.

Answer 2

Answer:

30°

Explanation:

Angle of incidence is equal to angle of reflection.
