Parts of a Wave

crest

Crest – the highest point of a wave.

trough

Trough – the lowest point of a wave.

Wavelength – a measure from one point on one wave to the corresponding point on

the next wave.

Measured in meters.

The distance a wave travels in a specific amount of time.

Meters per second

Wave Speed

Equilibrium

Equilibrium – rest position

Amplitude – the distance a wave rises or falls from the equilibrium.

(How big the wave is)You need more energy to make the amplitude

larger

Frequency – measurement of how many cycles can happen in a certain

amount of time.

Frequency is measured in hertz.

Example: If a motor makes 50 revolutions in one second, we say it has a frequency

of 50 hertz (Hz) per second.
