Chapter 12.1, Problem 7R

To determine

To Find: The reflected angle.

Answer to Problem 7R

The reflected angle is ${27}^{\circ }$ .

Explanation of Solution

Given:

Angle of incident is ${27}^{\circ }$ .

Calculation:

Angle of incident ray with respect to the normal is ${27}^{\circ }$ . Now incident angle = reflected angle. So, reflected angle is ${27}^{\circ }$ .

Conclusion:

Hence, the reflected angle is ${27}^{\circ }$ .
