Question

Answer fast........ For a given incident ray.A plane
mirror is turned through 15°. The reflected ray would turn
through.......​

Answer 1

15° is the reflected ray

angle of incidence=angle of reflection

Answer 2

Answer:

when a ray falls on a plane mirror which is a incident ray that is 15° then the reflected ray will be also same according to law of reflection angle of incidence = angle of reflection

so the angle of reflection is also 15°

I think this is the answer...........I hope it helps you
