A) \[0{}^\circ \]
B) \[90{}^\circ \]
C) \[180{}^\circ \]
D) none of these
Correct Answer: C
Solution :
The phenomenon of reflection is independent of medium. The deviation produced by combination of two plane mirrors is \[\delta =2\pi -2\theta \] \[\delta =2\pi -2.\frac{\pi }{2}\] \[(\because \theta ={{90}^{o}})\] \[=2\pi -\pi \] \[\delta =\pi ={{180}^{o}}\]You need to login to perform this action.
