Sound Waves

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) by vibrating particles.

Front

Can sound waves travel through space?

Back

No, sound waves cannot travel through space because there are no particles to transmit the vibrations.

Front

What is the formula for sound intensity?

Back

Sound intensity (I) is equal to sound power (P) divided by area (A): I = P/A.

What type of wave is a sound wave?

Back

A sound wave is both a mechanical wave and a longitudinal wave.

Front

What do sound waves require to travel?

Back

Sound waves require a medium (such as air, water, or solid materials) to travel.

Front

What is the relationship between sound intensity and distance?

Back

As the distance from the sound source increases, the intensity of the sound wave decreases.

Front

What is a mechanical wave?

Back

A mechanical wave is a wave that requires a medium to travel through, such as sound waves.

Front

What is a longitudinal wave?

Back

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

Front

What happens to sound waves in a vacuum?

Back

In a vacuum, sound waves cannot propagate because there are no particles to carry the sound.

Front

What is sound power?

Back

Sound power is the rate at which sound energy is emitted, reflected, transmitted, or received, measured in watts.
