Waves and Sound

Front

What do sound waves require to travel?

Back

Sound waves require a medium.

Front

What produces sound waves?

Back

Sound waves are produced by vibrating objects.

Front

What does the speed of a sound wave depend on?

Back

The speed of a sound wave depends on the air temperature.

Front

What is the unit of frequency?

Back

The Hertz is a unit of frequency.

Front

What type of wave causes particles to vibrate perpendicularly to the direction of wave travel?

Back

A transverse wave.

Front

What is a longitudinal wave?

Back

A wave that causes particles of the medium to vibrate parallel to the direction the wave travels.

Front

What is the relationship between frequency and wavelength in sound waves?

Back

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

Front

What is amplitude in the context of sound waves?

Back

Amplitude is the maximum displacement of particles from their rest position, related to the loudness of the sound.

Front

How does temperature affect the speed of sound?

Back

As temperature increases, the speed of sound in air increases.

Front

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

Back

In a transverse wave, particles move perpendicular to wave direction; in a longitudinal wave, particles move parallel.
