• Constructive

• Destructive

What type of interference is represented in the diagram?

• Constructive

• Destructive

What's happening at A?

• Two crests are combining to create constructive interference.

• A crest and a trough are combining to create destructive interference.

• Two crests are combining to create destructive interference.

• A crest and trough are combining to create constructive interference.

Through which material does sound travel slowest?

• Water

• Paper

• Aluminum

• Air

• None of the above

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.

When 2 waves temporarily interfere with each other then resume their course of movement, which of the following is true?

• They take on and keep a new amplitude based on the result of the interference until the end of the movement.

• They are not affected by the interference and maintain their original amplitude throughout the movement.

• Both waves are always counteracted and cease to exist.

• They temporarily take on a new amplitude due to the interference but resume their original amplitude until the end of the movement.
