UV Wavelengths

The portion of the electromagnetic spectrum with wavelengths shorter than visible light but longer than X-rays, known for having sterilizing properties and causing sunburn.

Action Spectrum

A graph of the effectiveness of light at specific wavelengths in promoting a light-requiring reaction. Compare with absorption spectrum.

Absorption Spectrum

A graph of the amount of light at specific wavelengths that is absorbed as light passes through a substance. Each type of molecule has a characteristic absorption spectrum. Compare with action spectrum.
