Sound Waves

Front

What is amplitude?

Back

Amplitude is the maximum extent of a vibration or oscillation, measured from the position of equilibrium. It determines the loudness of a sound.

Front

What is the process that produces sound?

Back

Sound is produced when something vibrates.

Front

What is the starting position in a wave?

Back

The starting position is the equilibrium position of a wave, where the wave would be if there were no disturbances.

Front

What is vibration?

Back

Vibration is a rapid back-and-forth motion that can occur in solids, liquids, or gases.

Front

What determines the pitch of a sound?

Back

The pitch of a sound is determined by the frequency of the sound waves.

Front

What is wavelength?

Back

Wavelength is the distance between successive crests or troughs of a wave.

Front

What is frequency?

Back

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

Front

What is a sound wave?

Back

A sound wave is a type of mechanical wave that travels through a medium (solid, liquid, or gas) due to vibrations.

Front

What is the relationship between amplitude and loudness?

Back

Higher amplitude means a louder sound, while lower amplitude means a softer sound.

Front

What is a medium in the context of sound?

Back

A medium is the substance through which sound waves travel, such as air, water, or solids.
