Question

a beam of light is incident on a concave mirror . if sum of angle of incidence and angle of reflection is90°then angle of incidence is degree is​

Answer 1

Answer:

45 degree is the answer

Answer 2

Answer:

Here is ur ans

Explanation:

If the angle between the incident ray and reflected ray is 90°, the angle of reflection is half of 90° i.e., 45° . Always, the angle of incidence = the angle of reflection. This means that the angle which the normal makes with the incident ray is the same as the angle which the normal makes with the reflected ray.
