Waves Review

Front

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

Back

Wavelength and frequency are inversely related; as one increases, the other decreases.

Front

What happens to the frequency if the wavelength is tripled?

Back

The frequency would be a third of what it was.

Front

How do you calculate the speed of a wave?

Back

Speed = Frequency x Wavelength.

Front

If a guitar string vibrates at a frequency of 320 Hz and the wavelength is 0.23 meters, what is the speed of the wave?

Back

74 m/s.

Front

What is the wavelength of a sound wave if the speed of sound is 150 m/s and the frequency is 100 Hz?

Back

1.5 meters.

Front

What happens to the wavelength if the frequency is doubled?

Back

The wavelength would be halved.

Front

What is the formula to find the wavelength of a wave?

Back

Wavelength = Speed / Frequency.

Front

If a wave has a frequency of 5 Hz and a speed of 25 m/s, what is the wavelength?

Back

5 meters.

Front

Define frequency in the context of waves.

Back

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

Front

What is the unit of measurement for wavelength?

Back

Wavelength is typically measured in meters (m).
