Answer:

If reflected ray is rotated by 4\Theta then mirror will be rotated by 2\Theta

Explanation:

At the point when the mirror is rotated at an angle theta , the incident ray will fall on the mirror making an angle  of 2 theta with the typical .

As we know that angle of incidence is always equal to angle of reflection

So if mirror is rotated by \Theta then reflected ray will also rotated by 2\Theta

In question it is given that reflected ray is rotated by 4\Theta

So mirror will be rotated by \frac{4\Theta }{2}=2\Theta
