Sound Waves

Front

What is sound?

Back

Sound is a type of energy made by vibrations that travels through air, water, or solids.

Front

How does sound travel through different mediums?

Back

Sound travels fastest through solids, slower through liquids, and slowest through gases due to the density and arrangement of molecules.

Front

What is the unit of measurement for sound intensity?

Back

The unit used to measure the volume of sound is the decibel (dB).

Front

What is frequency in relation to sound?

Back

Frequency is the number of vibrations or cycles per second of a sound wave, measured in hertz (Hz).

Front

What is pitch?

Back

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

Front

What is the Doppler Effect?

Back

The Doppler Effect is the change in frequency or wavelength of a wave in relation to an observer moving relative to the wave source.

Front

What happens to the pitch of a sound as the source approaches an observer?

Back

As the sound source approaches, the pitch increases; as it moves away, the pitch decreases.

Front

What is amplitude in sound waves?

Back

Amplitude refers to the height of the sound wave, which determines the loudness of the sound.

Front

What is a sound wave?

Back

A sound wave is a longitudinal wave that is created by vibrating objects and travels through a medium.

Front

What is resonance?

Back

Resonance is the phenomenon that occurs when an object vibrates at its natural frequency due to an external force.
