Frequency is the:

• size of a wave

• the speed of the wave

• the number of waves that passes a point in one second

• all of these

Frequency is measured in:

• grams

• meters

• litres

• Hertz

Delta waves have a frequency of ___ Hz.

You can tell a lot about a wave by looking at its parts.

The amplitude of a wave is the amount of energy carried by a wave. In a transverse wave, the amplitude is the height of the wave.

Wavelength is the distance between one point on a wave and the nearest point just like it. In a transverse wave, the wavelength is the distance from crest to crest or trough to trough.

Frequency is the number of waves that pass a given point in one second.
