Properties of waves

Waves involve movement that is repeated at regular intervals. Identify what this is called. 

•  Irregular motion

• Periodic motion

• Frequent motion

• Random motion

A cork is bobbing up and down on ocean waves. The time it takes to move up and down once, is the wave's:

• frequency

• colour

• period

• height

The ________ of a wave is how long is takes to go through its full motion once.

The distance between one crest of a wave and the next crest.

• Period

• Frequency

• Trough

• Wavelength

The frequency is how many waves go by in a minute

• True

• False

• True - frequency measures how many times it moves over a period of time

• False - frequency of a wave is measured per second

Answer explanation

Remember: frequency = how many waves go by in a second
