Front

What is frequency?

Back

Frequency is how many wavelengths are completed in one second.

Front

What is an example of a low pitch sound?

Back

A low pitch sound is a sound that has a lower frequency, such as a bass drum.

Front

What is an example of a high pitch sound?

Back

A high pitch sound is a sound that has a higher frequency, such as a whistle.

Front

How is frequency measured?

Back

Frequency is measured in Hertz (Hz).

Front

Which wave has a greater frequency, wave A or wave B?

Back

Wave A has a greater frequency than wave B.

Front

What does a higher frequency indicate about a sound?

Back

A higher frequency indicates a higher pitch sound.

Front

What does a lower frequency indicate about a sound?

Back

A lower frequency indicates a lower pitch sound.

Front

What is the relationship between wavelength and frequency?

Back

As frequency increases, wavelength decreases.

Front

What unit is used to measure sound frequency?

Back

Hertz (Hz) is the unit used to measure sound frequency.

Front

If a sound has a frequency of 440 Hz, what does that mean?

Back

It means that 440 wavelengths of the sound wave are completed in one second.
