Answer:
The light ray is reflected back into the opposite direction
Explanation:
The law of reflection states that when a light ray hits a reflecting surface, the angle of reflection (measured between the reflected ray and the normal to the surface) is equal to the angle of incidence (measured between the incident ray and the normal to the surface).
In this case, we have a light ray that it is incident along the normal to the surface: this means that the angle of incidence is . As per the law of reflection, the angle of reflection must be the same: . This means that the reflected ray is also along the normal, just in the opposite direction to that of the incident ray.
Because they perform different functions
