Question

A set of headphones produces sounds that cancel out sound waves from the

environment. Which wave interaction enables these headphones to work?

A. Constructive interference

B. Absorption

C. Destructive interference

D. Reflection

Answer 1

C. Destructive interference

Step-by-step explanation:

Destructive interference is when there are two waves with the same frequency, and the peaks of one wave (the highest points) line up with the valleys (the lowest points) of the second one.

Constructive interference would cause the sound to be louder.

Absorption and reflection are interactions that would not take into account the fact that the headphones produce sounds.
