Question

if the value of incidents angle is 30 then what will be the value of reflected in plane mirror​

Answer 1

Explanation:

Glancing angle of incidence is defined as the angle between the incident ray and the reflecting surface.

Hence, angle of incidence + glancing angle of incidence = 90

0

So, angle of incidence =90

0

− glancing angle of incidence =90

0

−30

0

=60

0

Answer 2

Answer:

30º

Explanation:

The law of reflection states that-

• The angle of incidence = The angle of reflection.

So, if the incidence ray is 30º, the reflected ray will also be 30º.

Hope this helps...
