Question

The angle between an incident

ray and the mirror is 40°.
1) What is the angle of reflection?​

Answer 1

1) 50°

Step-by-step explanation:

We need to find the angle of incidence first before finding the angle of reflection.

Angle of incidence = 90° - 40°

= 50°

Since the angle of incidence is the same as the angle of reflection, the angle of reflection here would be 50°.
