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 type of wave does sound travel in?

Back

Sound travels in a longitudinal wave.

Front

What is the speed of sound at 20 degrees Celsius?

Back

The speed of sound at 20 degrees Celsius is 343 m/s.

Front

If a wave chain represents 1 second, what is the frequency of the waves if there are 3 waves?

Back

The frequency of the waves is 3 Hz.

Front

What does it mean if an object is standing still in terms of motion?

Back

It means the object is not moving in any direction.

Front

Define 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.

Front

What are rarefactions in a longitudinal wave?

Back

Rarefactions are the parts of a longitudinal wave where the coils are spread apart.

Front

How is frequency defined in wave motion?

Back

Frequency is the number of waves that pass a given point in one second, measured in Hertz (Hz).

Front

What is the relationship between wavelength and frequency?

Back

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

Front

What is the formula for calculating wave speed?

Back

Wave speed = frequency × wavelength.
