- A 117.0W lightbulb emits about 7.45W of visible light. (The other 109.55W are emitted as infrared radiation or lost as heat to the surroundings.) The average wavelength of the visible light is about 570.0nm, so make the simplifying assumption that all the visible light has this wavelength. What is the frequency of the emitted visible light? How many visible-light photons does the bulb emit per second?arrow_forwardThere 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?
