Find the angle between the incident and the reflected ray.
A) \[{{65}^{\text{o}}}\]
B) \[{{90}^{\text{o}}}\]
C) \[{{130}^{\text{o}}}\]
D) 25
Correct Answer: C
Solution :
The angle between the incident ray and reflected ray \[=\left| \!{\nderline {\, i \,}} \right. +\left| \!{\nderline {\, r \,}} \right. \] From the given figure, \[\left| \!{\nderline {\, i \,}} \right. =90-25\] \[\left| \!{\nderline {\, i \,}} \right. ={{65}^{o}}=\left| \!{\nderline {\, r \,}} \right. \]and (laws of reflection) \[\left| \!{\nderline {\, i \,}} \right. +\left| \!{\nderline {\, r \,}} \right. ={{65}^{o}}+{{65}^{o}}={{130}^{o}}\]
