A) Perpendicular to each other
B) Parallel to each other
C) At an angle of \[{{90}^{\text{o}}}\]
D) At an angle of \[{{60}^{\text{o}}}\]
Correct Answer: B
Solution :
The two reflecting, plane mirrors arranged in a periscope are parallel to each other. The light ray from the object is incident on the first plane mirror at an angle of \[45{}^\circ \] and the reflected ray is incident on the second mirror at \[45{}^\circ \] and is then reflected at \[45{}^\circ \], which finally reaches the retina of the eye.You need to login to perform this action.
