Directions : In the following question more than one of the answers given may be correct. Select the correct answer and mark it according to the code:
A plane mirror reflecting a ray of incident light is rotated through an-abgle\[\theta \]about an axis through the point of incidence in the plane of the mirror perpendicular to the plane of incidence, then (1) the reflected ray does not rotate (2) the reflected ray rotates through angle\[2\theta \] (3) the reflected ray rotates through an angle\[\theta \] (4) the incident ray is fixedA) 1, 2 and 3 are correct.
B) 1 and 2 are correct.
C) 2 and 4 are correct.
D) 1 and 3 are correct.
Correct Answer: C
Solution :
By keeping the incident ray fixed, if plane mirror rotates through an angle\[\theta \]reflected ray rotates through an angle\[2\theta \].
