What term describes a ray of light going toward the mirror or other object?

• A. Incident ray
• B. Reflected ray
• C. Plane mirror
• D. Astigmatism

Answer: (A)

The incident ray describes the light ray moving toward a surface. It’s the incoming ray before it hits the mirror or any boundary. After it meets the surface, the light that bounces off is called the reflected ray, while a ray bending as it passes into another medium would be a refracted ray. A plane mirror is just a flat mirror, not the term for the incoming light, and astigmatism is a vision defect, not the description of the incoming light.
