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

Answer: (A)

When a wave meets a material, the energy can be reflected, transmitted, or absorbed. An absorber is the material that takes in the wave’s energy rather than bouncing it away or letting it pass through. That absorbed energy is typically converted to heat inside the material, which is why things like dark, matte surfaces heat up more in sunlight. A reflector is designed to bounce waves back, not to take them in. An insulator reduces heat transfer overall but isn’t defined by absorbing the wave energy itself. A conductor focuses on transmitting energy through it rather than absorbing it. So the term that describes a material that takes in a wave is absorber.
