27° (option C)
Explanation:
The angle of incidence of an incoming ray = 27°
To answer this queston, we will apply the law of reflection.
The law of reflection states that if any ray of light reflect from a smooth surface, the angle of incidence will be the same as the angle of reflection
Since the angle of incidence of the ray is 27°, then the angle of reflection for the same ray leaving the mirror will also be 27° (option C)
