Final answer:
The angle of reflection is 30° from the normal when a light ray hits a mirror at a 30° angle from the normal.
Step-by-step explanation:
When a light ray hits a mirror, the angle of incidence (the angle between the ray and the normal) is equal to the angle of reflection (the angle between the reflected ray and the normal). In this case, the light ray hits the mirror at a 30° angle from the normal, so the angle of reflection will also be 30° from the normal.
