Sound Waves

Front

What is frequency in the context of sound waves?

Back

Frequency refers to the number of vibrations or cycles of a sound wave that occur in one second, measured in Hertz (Hz).

Front

What unit is used to measure frequency?

Back

Frequency is measured in Hertz (Hz).

Front

What is the relationship between frequency and pitch?

Back

The pitch of a sound is determined by its frequency; higher frequencies result in higher pitches, while lower frequencies result in lower pitches.

Front

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

Back

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

Front

What happens to the pitch of a sound when the frequency decreases?

Back

When the frequency decreases, the pitch of the sound becomes lower.

Front

What is amplitude in the context of sound waves?

Back

Amplitude refers to the height of the sound wave, which determines the loudness or volume of the sound.

Front

How does changing the amplitude of a sound wave affect its volume?

Back

Increasing the amplitude makes the sound louder, while decreasing the amplitude makes the sound quieter.

Front

What is the effect of changing the frequency of a sound wave on its pitch?

Back

Changing the frequency of a sound wave directly affects its pitch; higher frequencies produce higher pitches, and lower frequencies produce lower pitches.

Front

What is wavelength in relation to sound waves?

Back

Wavelength is the distance between two consecutive points of the same phase in a sound wave, such as from crest to crest.

Front

How are frequency and wavelength related?

Back

Frequency and wavelength are inversely related; as frequency increases, wavelength decreases, and vice versa.
