Waves & Sound

Front

What are sound waves?

Back

Sound waves are vibrations that travel through air, water, or solids, allowing us to hear sounds.

Front

How do sound waves travel through different states of matter?

Back

Sound waves travel fastest through solids, slower through liquids, and slowest through gases due to the distance between particles.

Front

What is amplitude in relation to waves?

Back

Amplitude is the distance from the resting position to the crest (highest point) of a wave, indicating the energy of the wave.

Front

What is wavelength?

Back

Wavelength is the distance between two consecutive crests or troughs in 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 determines the pitch of a sound?

Back

The pitch of a sound is determined by the frequency of the sound wave; higher frequency means higher pitch.

Front

What happens when you pluck a guitar string?

Back

Plucking a guitar string causes it to vibrate, creating sound waves that we hear as music.

Front

How can you stop the sound from a vibrating string?

Back

You can stop the sound by placing your hand on the string to stop its vibration.

Front

What is the relationship between vibration and sound?

Back

Vibrations create sound waves; the faster the vibrations, the higher the pitch of the sound.

Why do thick rubber bands produce lower-pitched sounds than thin ones?

Back

Thick rubber bands vibrate more slowly than thin ones, resulting in lower-pitched sounds.
