Front

What unit is used to measure the frequency of a sound?

Back

Front

Frequency is a way to measure what aspect of sound?

Back

The pitch of a note.

Front

What does amplitude measure in sound?

Back

How loud or quiet a sound is.

Front

What unit is used to measure amplitude?

Back

Decibel (dB)

Front

Which wave shows a louder sound, A or B?

Back

Wave A shows a louder sound.

Front

What is the relationship between frequency and pitch?

Back

Higher frequency corresponds to a higher pitch.

Front

What is the range of human hearing in Hertz?

Back

Approximately 20 Hz to 20,000 Hz.

Front

What is the formula for calculating frequency?

Back

Frequency (f) = 1 / Period (T), where T is the time period of one cycle.

Front

How does sound travel through different mediums?

Back

Sound travels faster in solids than in liquids, and faster in liquids than in gases.

Front

What is the Doppler effect?

Back

The change in frequency or wavelength of a wave in relation to an observer moving relative to the wave source.
