Chapter SH, Problem 12.3APP

To determine

To calculate: Angle of incidence.

Answer to Problem 12.3APP

Angle of incidence is $\underset{\_}{52°}$

Explanation of Solution

Given:

Angle between incident ray and reflected ray = $104°$

Calculation:

According to the law of reflection of light, angle of incidence is equal to the angle of reflection,

Therefore,

Angle of reflection = Angle of incidence = $\frac{\text{104}°}{2}=52°$

Conclusion:

Angle of incidence is $\underset{\_}{52°}$
