Fluorescent light vs laser

WebA laser only emits light of high irradiance at a very narrow wavelength interval, typically under 0.01 nm, which makes an excitation monochromator or filter unnecessary. The disadvantage of this method is that the wavelength of a laser cannot be changed by much. A mercury vapor lamp is a line lamp, meaning it emits light near peak wavelengths. WebSep 27, 2011 · When light shines on the matter, it makes the electrons oscillate with the same frequency as the incident light. These oscillating electrons then re-radiate the same frequency of light.
