Front

What is visible light?

Back

Visible light is the portion of the electromagnetic spectrum that can be seen by the human eye.

Front

What is the relationship between wavelength and frequency?

Back

Wavelength and frequency are inversely related; as the wavelength increases, the frequency decreases.

Front

What is a wave?

Back

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