Sound Waves Review

Front

What is amplitude in sound waves?

Back

Amplitude refers to the height of the sound wave, which determines the loudness of the sound. Higher amplitude means louder sounds.

Front

What is the relationship between amplitude and loudness?

Back

Higher amplitude means higher loudness.

Front

What does low frequency mean in terms of pitch?

Back

Low frequency corresponds to low pitch.

Front

What causes sound to occur?

Back

Sound is caused by vibrations.

Front

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

Back

The pitch increases.

Front

What is a sonic boom?

Back

A sonic boom is a loud sound that occurs when an object travels faster than the speed of sound.

Front

What is frequency in sound waves?

Back

Frequency is the number of vibrations or cycles per second in a sound wave, measured in Hertz (Hz).

Front

How does frequency affect pitch?

Back

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

Front

What is the speed of sound?

Back

The speed of sound is the speed at which sound waves travel through a medium, approximately 343 meters per second in air at room temperature.

Front

What is the Doppler effect?

Back

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