Properties of Light and Sound Waves

Front

What is visible light?

Back

Visible light is that part of the electromagnetic spectrum that you can see.

Front

What are compressions in a sound wave?

Back

The pressed together regions of particles in a sound wave.

Front

What is required for sound to travel?

Back

A medium is required for sound to travel.

Front

Can sound waves travel through a vacuum?

Back

No, sound waves cannot travel through a vacuum (empty space).

Front

What is the Doppler Effect?

Back

The change in wave frequency due to a wave source moving relative to an observer or an observer moving relative to a wave source.

Front

What is a medium in the context of sound waves?

Back

A medium is a substance (solid, liquid, or gas) through which sound waves can travel.

Front

What is the speed of sound in air at room temperature?

Back

Approximately 343 meters per second.

Front

What is the difference between rarefactions and compressions in sound waves?

Back

Rarefactions are the regions where particles are spread apart, while compressions are where particles are pressed together.

Front

What is wavelength in relation to waves?

Back

Wavelength is the distance between two consecutive points of the same phase in a wave, such as crest to crest.

Front

What is frequency in the context of waves?

Back

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