Chapter SH, Problem 12.2APP

To determine

To calculate: Angle the reflected ray makes with the normal.

Answer to Problem 12.2APP

Angle between the reflected ray and normal is $\underset{\_}{65°}$

Explanation of Solution

Given:

Angle between light ray and surface of mirror = $25°$

Calculation:

Angle between normal and incident ray = $90-25=65°$

According to the law of reflection of light, angle between the incident ray and the normal (angle of incidence) is equal to the angle between reflected ray and the normal,

Therefore, angle between the reflected ray and normal = $65°$

Conclusion:

Angle between the reflected ray and normal is $\underset{\_}{65°}$
