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 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 happens to the frequency of a sound wave when the wavelength is long?

Back

The frequency is lower when the wavelength is long.

Front

How do sound waves travel?

Back

Sound waves travel outward in all directions from the source.

Front

What is a trough in a wave?

Back

A trough is the lowest point of a wave.

Front

What is the amplitude of a wave?

Back

Amplitude is the height of the wave from its midpoint to its peak or trough, indicating the loudness of the sound.

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 wavelength?

Back

Wavelength is the distance between two consecutive points of a wave, such as from one crest to the next crest.

Front

What is the speed of sound?

Back

The speed of sound is how fast sound waves travel through a medium, which varies depending on the medium (e.g., faster in water than in air).

Front

What is the difference between a high frequency and a low frequency sound?

Back

High frequency sounds have a higher pitch, while low frequency sounds have a lower pitch.
