What is frequency a measure of?

Back

The number of waves that pass a point in one second.

Front

Can electromagnetic (EM) waves travel through a vacuum?

Back

Yes, EM waves can travel through a medium or a vacuum.

Front

What happens to frequency when the wavelength increases?

Back

The frequency decreases.

Front

Where does visible light fall on the electromagnetic spectrum?

Back

Between infrared and ultraviolet.

Front

What is the amplitude of a wave?

Back

The height of a wave, measured from the point of rest or the mid-line to either the crest or the trough.

Front

What is the relationship between wavelength and frequency in waves?

Back

They are inversely related; as one increases, the other decreases.

Front

What is the speed of light in a vacuum?

Back

Approximately 299,792 kilometers per second (or about 300,000 km/s).

Front

What is the formula for calculating wave speed?

Back

Wave speed = frequency × wavelength.

Front

What are the two main types of waves?

Back

Transverse waves and longitudinal waves.

Front

What is a transverse wave?

Back

A wave in which the particle displacement is perpendicular to the direction of wave propagation.
