Measuring/Identifying waves

Front

What is a longitudinal wave?

Back

A wave in which the particles of the medium move parallel to the direction of the wave's propagation.

Front

Define compression in a longitudinal wave.

Back

The region in a longitudinal wave where particles are packed closely together.

Front

What is rarefaction in a longitudinal wave?

Back

The region in a longitudinal wave where particles are spread apart.

Front

What are the two main types of waves?

Back

Transverse waves and longitudinal waves.

Front

Define amplitude in the context of waves.

Back

The maximum displacement of points on a wave from its rest position.

Front

What is the formula for wave speed?

Back

Wave speed = frequency × wavelength.

Front

What is a crest in a transverse wave?

Back

The highest point of a transverse wave.

Front

What is a trough in a transverse wave?

Back

The lowest point of a transverse wave.

Front

What does wavelength represent in a wave?

Back

The distance between two consecutive points that are in phase on a wave, such as crest to crest.

Front

How do you calculate the frequency of a wave?

Back

Frequency = number of waves / time period.
