Question

when a plane mirror is rotated through an angle of 10 in clockwise direction and incident ray is rotated by 5 in anti clockwise direction by what angle will the reflectedbeam rotate ?​

Answer 1

Answer:

25 degrees

Step-by-step explanation:

on rotating the mirror and incident ray that way, angle of incidence becomes 15 degrees, and now angle of reflection is 15 from current scenario. change is 15 plus 10 = 25 degrees

Answer 2

Step-by-step explanation:

your answer is this and this because the angles of 10in clock wise
