Waves and Sound Activity 2

Front

What is pitch in sound waves?

Back

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

Front

What unit is used to measure the pitch of sound?

Back

The unit used to measure pitch is Hertz (Hz), which indicates the frequency of sound waves.

Front

What is the relationship between amplitude and volume in sound?

Back

Higher amplitude corresponds to higher volume, while lower amplitude corresponds to lower volume.

Front

What are mechanical waves?

Back

Mechanical waves are waves that require a medium (solid, liquid, or gas) to travel through.

Front

What is the unit used to measure the volume of sound?

Back

The unit used to measure the volume of sound is the decibel (dB).

Front

What happens to pitch as frequency increases?

Back

As frequency increases, the pitch of the sound becomes higher.

Front

What is a transverse wave?

Back

A transverse wave is a type of wave where the particle displacement is perpendicular to the direction of wave propagation.

Front

What is a longitudinal wave?

Back

A longitudinal wave is a type of wave where the particle displacement is parallel to the direction of wave propagation.

Front

How does sound travel in different mediums?

Back

Sound travels fastest in solids, slower in liquids, and slowest in gases due to the density and elasticity of the medium.

Front

What is the Doppler effect?

Back

The Doppler effect is the change in frequency or pitch of a wave in relation to an observer moving relative to the wave source.
