Question

It the angle between the plance mirror
and the incident xay is 90', What
are the angles o incidence and
reflection?​

Answer 1

Step-by-step explanation:

angle of incidence will be 90 degrees

and reflection should be 180 degrees

Answer 2

Answer:

0°

Step-by-step explanation:

The angle of incidence and angle of reflection is 0°. In every plane mirror, normal is perpendicular to the plane mirror. According to the question given above, angle between the plane mirror and the incident ray is 90° which implies that incident ray is perpendicular to the plane mirror. Since, the incident ray is overlapping on the normal, ∠i = 0°. According to the laws of reflection, ∠i = ∠r. So, ∠r = 0°.
