A material can be described as fluorescent if it absorbs light of a certain wavelength and emits light of a different wavelength. ... In UV lighting, florescent material emits light of a certain color and the fluorescence can be seen with the human eye.

What is fluorescence in simple terms?

Fluorescence is the light given off by certain substances when it absorbs light or other electromagnetic radiation. First the substance absorbs the energy, then it emits light. ... Fluorescence in the life sciences is a way of tracking biological molecules.
