Front

What is the typical human hearing range in terms of frequency?

Back

20 Hz to 20,000 Hz

Front

How does the amplitude of a sound wave affect its energy?

Back

Higher amplitude means higher energy.

Front

What happens to the pitch of a sound as the frequency increases?

Back

The pitch increases.

Front

Which of the following best describes the relationship between amplitude and loudness?

Back

Higher amplitude means higher loudness.

Front

What is a sound wave?

Back

A sound wave is a vibration that travels through a medium (like air) and can be heard when it reaches a person's or animal's ear.

Front

What is frequency in relation to sound waves?

Back

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

Front

What is amplitude in relation to sound waves?

Back

Amplitude is the height of the sound wave, which determines the loudness of the sound.

Front

What is the relationship between frequency and pitch?

Back

Higher frequency results in a higher pitch, while lower frequency results in a lower pitch.

Front

What medium do sound waves travel fastest in?

Back

Sound waves travel fastest in solids.
