Question

what is occurring when two waves traveling along the same medium meet and cancel each other out?
destructive interference
constructive interference
reflection
refraction

Explanation:

When two waves meet and cancel each other out, it's called destructive interference. In constructive interference, waves combine to create a larger - amplitude wave. Reflection is when a wave bounces back from a boundary, and refraction is when a wave changes direction as it passes from one medium to another.

Answer:

A. destructive interference
