WebChlorofluorocarbons ( CFCs ), first created back in 1928 as non-toxic non-flammable refrigerants, feature in a laboratory study published by Mario Molina and Sherwood Rowland that shows CFCs can break down ozone in the presence of high frequency UV light. They received a Nobel Prize in 1995. 1985 – Antarctic ozone hole discovered A black light lamp emits long-wave UV‑A radiation and little visible light. Fluorescent black light lamps work similarly to other fluorescent lamps, but use a phosphor on the inner tube surface which emits UV‑A radiation instead of visible light. Some lamps use a deep-bluish-purple Wood's glass optical filter that blocks almost all visible light with wavelengths longer than 400 nanometers. The pur…

Frequency of Light: The Color Spectrum and Visible Light

WebUV light should be invisible to our eyes, because of the wavelength. UV flashlights are often referred to as 365nm or 395nm. The 365 nm is deeper into the UV spectrum and has less visible light. Basically, 365nm is preferred over 395 for most applications where UV is needed. Some points to make: WebYellow light has a higher frequency and therefore it has higher energy such that electrons can escape from potassium metal.
