Lesson 4, 5 & 6 Cumulative Sound Review

Front

What is a rarefaction in a sound wave?

Back

A rarefaction is the area in a sound wave where there are fewer molecules and they are spread out.

Front

What do high-pitched waves look like?

Back

High-pitched waves have shorter wavelengths and are closer together.

Front

What is the distance between two compressions or two rarefactions called?

Back

What is the relationship between frequency and pitch?

Back

Higher frequency waves produce higher pitches, while lower frequency waves produce lower pitches.
