Sound Waves and Hearing

Front

What does pitch depend on?

Back

Pitch depends on frequency.

Front

Which feature of sound is determined by amplitude?

Back

Loudness is determined by amplitude.

Front

If distance C on the diagram increased, what would happen to the pitch?

Back

The pitch would be lower.

Front

What is the Doppler effect?

Back

The Doppler effect occurs when an observer moves towards a wave-making source, causing a change in frequency.

Front

Sound waves move more quickly through which type of matter?

Back

Sound waves move more quickly through dense matter.

Front

Define sound wave.

Back

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

Front

What is frequency in terms of sound?

Back

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

Front

What is amplitude in sound waves?

Back

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

Front

How does temperature affect the speed of sound?

Back

Sound travels faster in warmer temperatures because the molecules are moving more quickly.

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.
