Waves

Front

What is Amplitude?

Back

The measure of how far the particles of a wave travel from the rest position.

Front

In which medium do sound waves travel the fastest?

Back

Sound waves travel fastest in solids.

Front

What are rarefactions in longitudinal waves?

Back

Rarefactions are the parts where the coils are spread apart.

Front

What does the letter 'D' represent in a wave diagram?

Back

The trough of the wave.

Front

What does low amplitude indicate about sound?

Back

Low amplitude indicates quieter sounds.

Front

What is Wavelength?

Back

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

Front

What is a Compression in a wave?

Back

A region in a longitudinal wave where the particles are closest together.

Front

What is the difference between transverse and longitudinal waves?

Back

In transverse waves, particles move perpendicular to the direction of wave travel; in longitudinal waves, particles move parallel to the direction of wave travel.

Front

What is the formula for wave speed?

Back

Wave speed = frequency × wavelength.

Front

What is Frequency?

Back

The number of waves that pass a given point in one second, measured in Hertz (Hz).
