Find the angle between the incident ray and the reflected ray.
A) \[{{60}^{\text{o}}}\]
B) \[{{90}^{\text{o}}}\]
C) \[{{80}^{\text{o}}}\]
D) \[{{40}^{\text{o}}}\]
Correct Answer: C
Solution :
\[\angle i={{40}^{o}}\](given) \[\angle i=\angle r={{40}^{o}}\] The angle between the incident ray and the reflected ray \[=\angle i+\angle r\] \[={{40}^{o}}+{{40}^{o}}={{80}^{o}}\]
