Sound waves

Front

What is a pitch?

Back

The highness or lowness of a sound.

Front

What happens to the amplitude when a sound is louder?

Back

The amplitude increases.

Front

Which sound has more kinetic energy?

Back

The sound with a higher amplitude has more kinetic energy.

Front

What is an echo?

Back

An echo is the sound that is reflected off a hard surface and heard again.

Front

What is the amplitude of a sound wave?

Back

The amplitude is the maximum extent of a vibration or oscillation, measured from the position of equilibrium.

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

How does wavelength relate to sound?

Back

Wavelength is the distance between successive crests of a wave, which affects the pitch 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 is volume in terms of sound?

Back

Volume is the perceived loudness of a sound, which is related to the amplitude of the sound wave.

Front

What is the speed of sound?

Back

The speed of sound is the distance traveled per unit of time by a sound wave through a medium.
