Sound Waves Review

Front

What is sound?

Back

Sound is a type of energy made by vibrations that travels through a medium (solid, liquid, or gas) as waves.

Front

What is a medium in the context of sound waves?

Back

A medium is a substance through which sound waves travel, such as air, water, or solid materials.

Front

How does the speed of sound vary in different mediums?

Back

Sound travels fastest in solids, slower in liquids, and slowest in gases due to the density and elasticity of the medium.

Front

What type of wave is a sound wave?

Back

A sound wave is a longitudinal wave, where the particle displacement is parallel to the direction of wave propagation.

Front

What is frequency in relation to sound?

Back

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

Front

What is pitch?

Back

Pitch is the perceived frequency of a sound; higher frequencies correspond to higher pitches, while lower frequencies correspond to lower pitches.

Front

What is compression in a sound wave?

Back

Compression is the part of a sound wave where particles are close together, resulting in higher pressure.

Front

What is rarefaction in a sound wave?

Back

Rarefaction is the part of a sound wave where particles are spread apart, resulting in lower pressure.

Front

How does temperature affect the speed of sound?

Back

Sound travels faster in warmer air because the air particles move faster and collide more often.

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.
