Final answer:
When a ray of light falls normally on the surface of a mirror, it is reflected back in the same direction.
Step-by-step explanation:
When a ray of light falls normally on the surface of a mirror, it is reflected back in the same direction. This is because the angle of reflection is equal to the angle of incidence. The mirror has a smooth surface and reflects light at specific angles. This is referred to as specular reflection, and it allows us to see clear mirror images. The law of reflection describes the behavior of light waves when they interact with a smooth surface, such as a mirror.
