There are several proteins that exist in nature that are fluorescent, which means they absorb visible light or other electromagnetic radiation and reemit that light, usually at a longer wavelength. One of the more prevalent fluorescent proteins is GFP, or green fluorescent protein, which emits bright green fluorescent light when exposed to light in the blue to ultraviolet region of the electromagnetic spectrum (see the photo). The main absorption, or excitation, wavelength for one type of GFP is 395 nm. (a) What is the energy (in eV) of a photon in this absorbed light? The emission spectrum of the light from the GFP peaks near 509 nm, which is in the shorter wavelength (higher energy) portion of the green part of the visible spectrum.
