Sound Waves

Front

What is pitch?

Back

Pitch refers to how high or low a sound seems to a person.

Front

Why can't sound waves travel through a vacuum?

Back

Sound waves cannot travel through a vacuum because there are no particles to travel through and vibrate.

Front

What type of wave does sound travel as?

Back

Sound travels as a longitudinal wave.

Front

What is the Doppler effect?

Back

The Doppler effect is the change in pitch of a sound as the source moves relative to an observer.

Front

What is intensity in terms of sound?

Back

Intensity refers to the power of sound per unit area, often perceived as loudness.

Front

What is the relationship between frequency and pitch?

Back

Higher frequency sound waves produce higher pitch sounds, while lower frequency waves produce lower pitch sounds.

Front

What is a longitudinal wave?

Back

A longitudinal wave is a wave in which the particles of the medium move parallel to the direction of the wave's travel.

Front

What is an example of sound traveling through a medium?

Back

An example is sound traveling through air, where air molecules vibrate to transmit the sound.

Front

What happens to sound waves as they travel further from the source?

Back

As sound waves travel further from the source, they lose intensity and become quieter.

Front

What is resonance in sound?

Back

Resonance is the phenomenon where an object vibrates at a specific frequency, amplifying the sound.
