Question

A ray of light is incident on a
plane mirror and the angle of
incidence is 15 degree. What is
the angle of reflection​

Answer 1

Answer:

please mark as brainliest

Explanation:

angle of incidence =90-15°

=75°

angle of reflection =75°

Angle between them is 90°

Answer 2

Answer:

The incident ray will have an angle of reflection of 60 degrees (made with a surface normal to the mirror surface). The reflected ray will make an angle of 30 degrees (90 - 60 degrees) with the mirror surface
