Waves Final Review

Front

What is a longitudinal wave?

Back

A wave in which the particles of the medium move back and forth in the same direction as the wave.

Front

Can sound travel through a vacuum?

Back

No, sound cannot travel through a vacuum; it requires a medium (solid, liquid, or gas) to propagate.

Front

What happens to the wavelength of high-pitched sounds?

Back

High-pitched sounds have shorter wavelengths, meaning they are close together.

Front

What is a mechanical wave?

Back

A wave that requires a medium to travel through, such as sound waves.

Front

What do all waves carry?

Back

All waves carry energy.

Front

What is the difference between a transverse wave and a longitudinal wave?

Back

In a transverse wave, particles move perpendicular to the direction of the wave, while in a longitudinal wave, particles move parallel to the direction of the wave.

Front

What is frequency in relation to waves?

Back

Frequency is the number of waves that pass a point in one second, measured in hertz (Hz).

Front

What is amplitude?

Back

Amplitude is the maximum displacement of particles from their rest position in a wave, related to the energy of the wave.

Front

What is the relationship between wavelength and frequency?

Back

Wavelength and frequency are inversely related; as frequency increases, wavelength decreases.

Front

What is a vacuum?

Back

A vacuum is a space devoid of matter, where sound cannot travel.
