Ocean Waves

Front

What is salinity?

Back

Salinity is a measure of how salty the water is.

Front

How do you determine wave speed?

Back

To determine wave speed, divide the wavelength by the wave period.

Front

If an ocean wave has a wavelength of 8 m and a wave period of 4 s, what is the wave speed?

Back

The wave speed is 2 m/s.

Front

What are the main parts of a wave?

Back

The main parts of a wave are: I. Amplitude, II. Crest, III. Wavelength, IV. Trough.

Front

What distinguishes a tsunami from other types of ocean waves?

Back

A tsunami forms when a large volume of water is suddenly displaced up or down.

Front

What is a wave crest?

Back

A wave crest is the highest point of a wave.

Front

What is a wave trough?

Back

A wave trough is the lowest point of a wave.

Front

What is wave amplitude?

Back

Wave amplitude is the height of the wave from the rest position to the crest.

Front

What is wavelength?

Back

Wavelength is the distance between two consecutive crests or troughs in a wave.

Front

What is wave period?

Back

Wave period is the time it takes for one complete wave to pass a given point.
