Topic 3 Lesson 1: Wave Properties

Front

What is a crest in a wave?

Back

The high points of a transverse wave.

Front

What is a trough in a wave?

Back

The low points of a transverse wave.

Front

What does wavelength refer to?

Back

The distance between two consecutive crests or troughs in a wave.

Front

What is amplitude in a wave?

Back

The height of the wave from its rest position to its crest or trough.

Front

What is frequency in terms of waves?

Back

The number of times a wave completes a cycle in a certain amount of time.

Front

What are transverse waves?

Back

Waves where the motion of the medium is perpendicular to the direction of the wave.

Front

What are longitudinal waves?

Back

Waves where the motion of the medium is parallel to the direction of the wave.

Front

What is an example of a transverse wave?

Back

Light waves and waves on a string.

Front

What is an example of a longitudinal wave?

Back

Sound waves.

Front

How do you measure wavelength?

Back

By measuring the distance from one crest to the next crest.
