Waves Review

Front

What are compressions in a longitudinal wave?

Back

Compressions are the parts of a longitudinal wave where the coils are close together.

Front

What is the medium through which sound travels fastest?

Back

Sound travels fastest through wood.

Front

What happens to the wavelength of a wave as the frequency increases?

Back

As the frequency of a wave increases, the wavelength decreases.

Front

In a high frequency wave, what is the part labeled 'B' if it is a trough?

Back

The part labeled 'B' is the trough, which is the lowest point of the wave.

Front

Which wave has the longest wavelength: top wave or bottom wave?

Back

The top wave has the longest wavelength.

Front

Define wavelength.

Back

Wavelength is the distance between two consecutive crests or troughs in a wave.

Front

What is a crest in a wave?

Back

A crest is the highest point of a wave.

Front

What is a trough in a wave?

Back

A trough is the lowest point of a wave.

Front

What is the relationship between frequency and amplitude in waves?

Back

Frequency and amplitude are independent; increasing frequency does not affect amplitude.

Front

What is a longitudinal wave?

Back

A longitudinal wave is a wave in which the particles of the medium move parallel to the direction of the wave's propagation.
