Document Summary

Chem 101-principles of chemistry: microwave radiation has a wavelength on the order of 1. 0 cm. Calculate the frequency and the energy of a single photon of this radiation. Calculate the energy of this radiation in kj/mol. Date: 3/9/2015: the wavelength of a green light from a traffic signal is centered at 522 nm. What is the frequency of this radiation in ghz: the work function of an element is the energy required to remove an electron from the surface of the solid substance. The work function for lithium is 279. 7 kj/mol (that is, it takes 279. 7 kj of energy to remove one mole of electrons from one mole of li atoms on the surface of li metal). If the wavelength of the particle is 1. 5 10-15 calculate the mass of the particle. m: calculate the wavelength of light emitted for each of the following transitions in the hydrogen atom.
