Problem- Iron vapor produces an emission spectrum that includes an intense peak at 527.0 nm. Determine the frequency (in Hz) for this type of electromagnetic radiation. What color of visible light corresponds to this wavelength? What is the energy (in J) per photon emitted at this wavelength? What is this photon energy in units of kJ per mole? (In other words, one mole of these photons with wavelength of 527.0 nm consists of how many kilojoules of electromagnetic energy?)
Please illustrate work as well as walk me during the problem so that I can follow and understand it
