The angle between the incident ray and the reflected ray is 60°. Then the value of the angle of incidence is ____ degrees.

The angle between the incident ray and the reflected ray is

60 °

. Then the value of the angle of incidence is

30 degrees

.
Given,
The angle between the incident ray and the reflected ray

= 60 °

According to the law of reflection,

the angle of incidence (θ_{i}) = angle of reflection (θ_{r})

So, the Sum of the angle of incidence and the angle of reflection

= θ_{i} + θ_{r}

\Rightarrow 60 °

i.e. The angle between the incident ray and the normal

= \frac{60 °}{2}

\Rightarrow 30 °

Therefore, the angle of incidence

θ_{i} = 30 °

The angle between the incident ray and the reflected ray is $60 °$ . Then the value of the angle of incidence is ____ $degrees$ .
