The term for a material that reflects waves is called the

• A. Reflector
• B. Absorber
• C. Conductor
• D. Insulator

Answer: (A)

Waves interact with surfaces by reflecting, transmitting, or absorbing. A material that sends energy back toward the source is called a reflector because it has high reflectivity and mainly redirects the wave rather than absorbing it. For example, a polished metal surface reflects infrared or visible light, and a parabolic dish reflects radio waves to a focal point. An absorber, in contrast, is designed to take in energy and convert it to heat, reducing what gets reflected. Conductors and insulators relate to how easily electric current or heat flows through a material, not to reflecting waves.
