The light ray makes angle of 30° with the plane of mirror, so it will make an angle of 60° with the normal.
Now according to the law of reflection,
incidence angle = reflection angle
(with the normal)
so,
The light ray will suffer a deviation of 60° + 60° = 120°, from original path.
Hope it helps you if yes then please mark my answer as brainliest ☺️☺️
