The angle between the incident ray and the reflected ray is\[80{}^\circ \]. What is the angle of incidence?
A) \[40{}^\circ \]
B) \[80{}^\circ \]
C) \[50{}^\circ \]
D) \[100{}^\circ \]
Correct Answer: A
Solution :
By drawing a normal, we find that the angle of incidence \[=\frac{80{}^\circ }{2}=40{}^\circ \]
