What is the definition of frequency?

• “how high” the wave is. It is the maximum distance the air particles travel from undisturbed position.

• The distance between one wave and the same point on the next wave usually measured in metres (m).

• The number of waves produced by a source each second. It is measured in Hertz (Hz).

What does a wave carry from place to place?

• energy

• matter

• people
