What is the process called when a crest interferes with a trough to lessen or cancel the amplitude of a wave.

• Constructive interference

• Destructive interference

When a crest and trough of two different waves interact you _________ the amplitudes.

• add

• subtract

• multiply

• divide

When the ___________ of the crest and trough are equal in magnitude (size) when the waves interact they will cancel each other out completely.
