Chapter 12.1, Problem 6R

To determine

To Find: The reflected angle.

Answer to Problem 6R

The reflected angle is ${48}^{\circ }$ .

Explanation of Solution

Given:

Angle of incident ray with the surface of the mirror is ${42}^{\circ }$ .

Calculation:

Angle of incident ray with respect to the surface of the mirror is ${42}^{\circ }$ . Therefore incident angle is ${90}^{\circ }-{42}^{\circ }={48}^{\circ }$ . Now incident angle = reflected angle. So, reflected angle is ${48}^{\circ }$ .

Conclusion:

Hence, the reflected angle is ${48}^{\circ }$ .
