Front

What does a waveform show?

Back

Front

What is pitch?

Back

How low (deep) or high (squeaky) a sound is.

Front

How does amplitude affect sound?

Back

Higher amplitude means louder sound.

Front

How does wavelength affect sound?

Back

Shorter wavelength means higher pitch.

Front

What is a sound wave?

Back

A wave that carries sound through a medium.

Front

What is the relationship between amplitude and energy?

Back

Higher amplitude means more energy in the wave.

Front

What happens to sound waves in a vacuum?

Back

They cannot travel because there is no medium.
