Question

If the angle of incidence of a light ray on a plane mirror is 400 , the angle between incident and reflected ray is (A) 500 (B) 1000 (C) 800 (D) 900 ​

Answer 1

Answer:

The angle at which a ray is incident is same as the angle at which the rays gets reflected.

So, angle between the incident ray and the reflected ray= 2( angle of incidence)

=2×50

o

=100

o

Answer 2

Answer:

IT WILL BE 800

Explanation:

Full explanation

- As we know that

Angle of incidence = Angle of reflection

Given

Angle of incidence = 400

therefore angle of reflection = 400

so angle between them = angle of incidence + angle of reflection

= 400 + 400 = 800
