When a compression interferes with another compression, what occurs?

• They counteract and the wave stops.

• They combine to create a larger compression.

• They combine to create a rarefaction.

• None of the above.

When a crest and a trough interfere, what occurs?

• They combine to create a higher amplitude wave.

• They counteract and the wave stops.

• The wave changes into a longitudinal wave.

• They combine to create a low amplitude wave.

Constructive interference happens when two waves are:

• out of phase.

• zero amplitude.

• in phase.
