angle of incident is always equal to the angle of reflection
so,
angle of reflection =40°
so,
angle of reflection =40°

since angle of incidence is equal to the angle of reflection the second law of reflection the angle of reflection will also make an angle of 40° with the plane mirror when the angle of incidence makes an angle of 40°
but the answer is 50°
because the incident Ray with plane surface together makes 40° so if we do 90-40 we get 50°which is angle of incidence . so according to the second law of reflection the angle of reflection will be 50°
