Sound Wave Properties

Front

What are sound waves?

Back

Sound waves are vibrations that travel through a medium (like air, water, or solids) and can be heard when they reach a person's or animal's ear.

Front

What is amplitude in sound waves?

Back

Amplitude refers to the height of the sound wave. It determines the volume or loudness of the sound; higher amplitude means louder sound.

Front

What is frequency in sound waves?

Back

Frequency is the number of waves that pass a point in one second. It determines the pitch of the sound; higher frequency means a higher pitch.

Front

How does changing the amplitude affect sound?

Back

Increasing the amplitude makes the sound louder, while decreasing it makes the sound quieter.

Front

How does changing the frequency affect sound?

Back

Increasing the frequency raises the pitch of the sound, while decreasing it lowers the pitch.

Front

What is the relationship between amplitude and volume?

Back

Volume is directly related to amplitude; greater amplitude results in a louder volume.

Front

What is the relationship between frequency and pitch?

Back

Pitch is directly related to frequency; higher frequency results in a higher pitch.

Front

What happens to sound waves when they travel through different mediums?

Back

Sound waves travel at different speeds in different mediums; they travel fastest in solids, slower in liquids, and slowest in gases.

Front

What is wavelength in sound waves?

Back

Wavelength is the distance between two consecutive peaks (or troughs) of a wave. It is inversely related to frequency.

Front

What is the speed of sound?

Back

The speed of sound is the distance sound travels in a given amount of time, typically around 343 meters per second in air at room temperature.
