What is the term for the bouncing of light off a surface?

• A. Refraction
• B. Reflection
• C. Diffraction
• D. Absorption

Answer: (B)

The term for the bouncing of light off a surface is reflection. When light encounters a surface, it can change direction and travel away from that surface, which is the essence of reflection. This phenomenon is observed when light hits mirrors or shiny surfaces, resulting in the clear images we see in these materials.

To further clarify, refraction involves the bending of light as it passes from one medium to another, such as from air into water, which alters its speed and direction. Diffraction refers to the bending and spreading of waves around obstacles or openings, causing patterns of light and shadow. Absorption is the process whereby the energy of light is taken in by a material, rather than being reflected or transmitted. Each of these concepts pertains to the behavior of light but specifically, only reflection describes the bouncing of light off a surface.
