Sound Waves Practice

Front

What determines the pitch of a sound?

Back

The pitch of a sound depends on its frequency.

Front

What is the relationship between frequency and pitch?

Back

A sound with a high pitch has a high frequency.

Front

What is NOT needed for sound to travel?

Back

A solid is not needed for sound to travel; sound can travel through gases and liquids.

Front

How can you identify a sound wave with high frequency?

Back

A sound wave with high frequency will have more waves per second compared to lower frequency waves.

Front

Why are carpets used in libraries?

Back

Carpets help absorb sounds to keep the environment quiet.

Front

What is amplitude in relation to sound waves?

Back

Amplitude refers to the height of the sound wave and is related to the loudness of the sound.

Front

What is the medium in which sound travels?

Back

The medium can be a solid, liquid, or gas through which sound waves propagate.

Front

How does sound travel through different mediums?

Back

Sound travels fastest in solids, slower in liquids, and slowest in gases due to the density and particle arrangement.

Front

What is the difference between loudness and intensity?

Back

Loudness is the perception of sound, while intensity is the physical measurement of sound energy.

Front

What happens to sound waves when they hit a soft surface?

Back

They are absorbed, which reduces echo and noise.
