PS: 7.2 Study Guide: Measuring Waves

In a longitudinal wave, amplitude is a measure of

• how many waves pass a fixed point each second.

• how close together particles of the medium become.

• how quickly the wave travels a given distance.

• how far apart adjacent compressions are.

If two waves have the same amplitude, the wave with more energy is the wave with the

• shorter wavelength.

• lower frequency.

• denser medium.

• slower speed.

If two waves have the same speed, the wave with a higher frequency must have a

• shorter wavelength.

• longer wavelength.

• greater amplitude.

• two of the above

Wave speed is a product of

• wavelength and frequency.

• wavelength and amplitude.

• frequency and amplitude.

What is the frequency of a wave that has a wavelength of 2 m and a speed of 2 m/s?

• 4 Hz

• 2 Hz

• 1 Hz

• 1/2 Hz

One measure of wave size is wave frequency.

• True

• False

The resting position of a transverse wave is called a trough.

• True

• False

If you know only a wave’s amplitude and wavelength, you can calculate its speed.

• True

• False

Wave speed and wavelength have an inverse relationship.

• True

• False

A tsunami is an ocean wave with an unusually great amplitude.

• True

• False
