Front

What is amplitude in relation to sound waves?

Back

Amplitude is the measure of the amount of energy in a wave, indicating how loud the sound is.

What are compressions in sound waves?

Back

Compressions are areas of increased pressure in a sound wave.

Front

What are rarefactions in sound waves?

Back

Rarefactions are areas of decreased pressure in a sound wave.

Front

What is frequency?

Back

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

Front

What is the relationship between frequency and pitch?

Back

Higher frequency sound waves produce higher pitch sounds, while lower frequency sound waves produce lower pitch sounds.
