Sound Waves

Front

What is a sound wave?

Back

A sound wave is a type of wave that travels through air, water, or solid materials, carrying sound energy from one place to another.

Front

What is frequency in relation to sound waves?

Back

Frequency is the number of waves that pass a point in one second, measured in Hertz (Hz). Higher frequency means a higher pitch.

Front

What is wavelength?

Back

Wavelength is the distance between two consecutive crests or troughs in a wave.

Front

What is amplitude?

Back

Amplitude is the height of a wave from its rest position to its crest or trough, which determines the loudness of the sound.

Front

How does wavelength affect frequency?

Back

A sound wave with a long wavelength has a lower frequency, while a sound wave with a short wavelength has a higher frequency.

Front

What is pitch?

Back

Pitch is how high or low a sound is, which is determined by the frequency of the sound wave.

Front

What happens to sound waves as they travel through different materials?

Back

Sound waves travel at different speeds depending on the material; they travel fastest in solids, slower in liquids, and slowest in gases.

Front

What is the relationship between amplitude and loudness?

Back

Higher amplitude means a louder sound, while lower amplitude means a softer sound.

Front

What is a crest in a sound wave?

Back

A crest is the highest point of a wave.

Front

What is a trough in a sound wave?

Back

A trough is the lowest point of a wave.
