Wave Properties

Front

What is the height of a wave called?

Back

Amplitude is the height of a wave from its rest position.

Front

What type of wave travels up and down?

Back

Transverse waves travel up and down.

Front

When more energy is added to a wave, its amplitude does what?

Back

The amplitude increases when more energy is added to a wave.

Front

Which of these is true of sound waves?

Back

Sound waves require particles to work.

Front

Why can't sound be heard in a vacuum?

Back

Sound cannot be heard in a vacuum because there are no particles.

Front

What is the distance between two consecutive wave crests called?

Back

Wavelength is the distance between two consecutive wave crests.

Front

What is a wave that moves in the same direction as the energy called?

Back

Longitudinal waves move in the same direction as the energy.

Front

What happens to the wavelength when the frequency of a wave increases?

Back

The wavelength decreases when the frequency increases.

Front

What is the term for the number of waves that pass a point in one second?

Back

Frequency is the number of waves that pass a point in one second.

Front

What is the term for the lowest point of a wave?

Back

The lowest point of a wave is called the trough.
