Behaviors of Waves Review

Front

What is the term for the number of waves that pass a point in one second?

Back

Frequency

Front

What type of interference occurs when two waves combine to form a wave of lesser amplitude?

Back

Destructive interference

Front

What must be true for two waves to undergo destructive interference?

Back

They must be out of phase.

Front

How do particles move in a longitudinal wave?

Back

Particles move parallel to the wave direction.

Front

What type of interference occurs when two waves combine to form a wave of greater amplitude?

Back

Constructive interference.

Front

Define amplitude in the context of waves.

Back

Amplitude is the maximum displacement of points on a wave from its rest position.

Front

What is wavelength?

Back

Wavelength is the distance between successive crests or troughs of a wave.

Front

What is the relationship between frequency and wavelength in a wave?

Back

Frequency and wavelength are inversely related; as frequency increases, wavelength decreases.

Front

What is a wave?

Back

A wave is a disturbance that transfers energy through space or matter.

Front

What is the difference between transverse and longitudinal waves?

Back

In transverse waves, particles move perpendicular to the wave direction; in longitudinal waves, particles move parallel.
