Which term means to cast back light, heat, or sound from a surface?

• A. Reflect
• B. Refract
• C. Scatter
• D. Solar

Answer: (A)

Reflection is the behavior of waves when they strike a surface and bounce back. This explains why you see images in a mirror—light reflects off the smooth surface—and why you hear echoes when sound hits a hard wall. Some surfaces can also reflect heat (thermal radiation), cooling or warming a space depending on the material. Refraction would be the bending of waves as they pass into a different medium, not bouncing back. Scatter means energy spreads in many directions, not a single bounce, and solar isn’t describing a bouncing process. So the term that means to cast back light, heat, or sound from a surface is reflection.
