Radiation in the ultraviolet region of the electromagnetic spectrum is quite energetic. It is this radiation that causes dyes to fade and your skin to develop a sunburn. If you are bombarded with 1.00 mol of photons with a wavelength of 345 nm, what amount of energy, in kilojoules per mole of photons, are you being subjected to? Energy = kJ/mol

The illustration shows the spectrum of electromagnetic radiation emitted by a blackbody at two different Kelvin temperatures. The range of visible frequencies (those that can be detected by the human eye) is also shown.(a) No matter what the value of the Kelvin temperature T, the spectrum decreases to zero at very high frequencies. Why is this?(i) At very high frequencies the photon energy is very small compared to kT.(ii) At very high frequencies the photon energy is very large compared...
