Question

6. If the reflected ray is
reflected ray is rotated by an angle of 4 theta in clockwise
direction then the mirror was rotated by
(al 2theta in anti-clockwise direction
(b) 4 theta in anti-clockwise direction
(c) 2 theta in clockwise direction
(d) 4theta in clockwise direction. Pls give relevant answers . Don't run for points . It is nice learning app. where the students can clarrify their doubts​

Answer 1

Answer:

no idea dear..............................................

Answer 2

Answer:

4 theta in anti-clockwise direction

Explanation:

as the reflected ray is rotated by 4 theta in clockwise direction, that means incident ray is rotated by 4 theta, so to keep the keep the reflected ray the same, mirror has to be rotated in anti-clockwise Direction at 4 theta

well the questions asks, reflected ray is rotated by 4 theta, so that does mean incident ray, coz reflected ray can only be rotated by the rotation of incident ray
