Sound

Front

What determines the energy of a mechanical wave?

Back

Amplitude.

Front

Can sound waves travel through a vacuum?

Back

False, sound waves require a medium to travel.

Front

What type of waves are sound waves?

Back

Longitudinal waves.

Front

What is the relationship between low frequency and pitch?

Back

Low frequency corresponds to low pitch.

Front

What does the speed of sound depend on?

Back

The medium through which it is moving.

Front

What is the definition of amplitude in the context of sound waves?

Back

Amplitude is the maximum displacement of points on a wave, which determines the loudness of the sound.

Front

What is frequency in relation to sound?

Back

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

Front

How does temperature affect the speed of sound?

Back

The speed of sound increases with an increase in temperature.

Front

What is the relationship between wavelength and frequency?

Back

Wavelength is inversely proportional to frequency; as frequency increases, wavelength decreases.

Front

What is pitch?

Back

Pitch is the perceived frequency of a sound, determining how high or low it sounds.
