Properties of Sound and Waves

Front

What is sound?

Back

Sound is a type of energy made by vibrations that travel through the air or another medium.

Front

What is a wave?

Back

A wave is a disturbance that transfers energy from one place to another without transferring matter.

Front

What is frequency?

Back

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

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, indicating the energy of the wave.

Front

How does frequency affect wavelength?

Back

As frequency increases, wavelength decreases, and vice versa.

Front

What medium does sound travel fastest in?

Back

Sound travels fastest in solids because the particles are closer together.

Front

What is a transverse wave?

Back

A transverse wave is a wave where the particles move perpendicular to the direction of the wave's travel.

Front

What is a longitudinal wave?

Back

A longitudinal wave is a wave where the particles move parallel to the direction of the wave's travel.

Front

What is the speed of sound in air?

Back

The speed of sound in air at room temperature is approximately 343 meters per second.
