A ray of light is incident on a plane mirror and the angle of reflecti...
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 x 50
= 100.

Calculation of angle between incident and reflected ray

Given:
- Angle of reflection = 50 degrees

To find:
- Angle between incident ray and reflected ray

Formula:
- According to the law of reflection, the angle of incidence is equal to the angle of reflection. Therefore, the angle between incident ray and reflected ray is twice the angle of reflection.

Solution:
- Angle between incident ray and reflected ray = 2 x 50 degrees = 100 degrees

Answer:
- The angle between incident ray and reflected ray is 100 degrees. Therefore, the correct option is (B) 100.
