Question

2. If a ray of light is incident on a plane mirror such that it makes an
angle of 30° with the mirror,
then what will be the angle of reflection?​

Answer 1

$\huge \bold \blue{90-30=60}$

Answer 2

Explanation:

$\huge \boxed {\pink{\bold{Answer}}}$

Since, angle of incidence = angle of reflection = 30 degrees. The incident ray will have an angle of reflection of 30 degrees (made with a surface normal to the mirror surface). Angle of incidence = 90 - angle made with the mirror surface= 90 - 60 = 30 degrees.
