Unformatted text preview: Calculate the energy of the n = 3 state of the H atom in joules per atom and kilojoules per mole. Calculate the wavelength of the green line in the visible spectrum of excited H atoms using the Bohr theory. The Lyman series of spectral lines for the H atom occurs in the ultraviolet region. They arise from transitions form higher levels to n = 1. Calculate the frequency and wavelength of the least energetic line in this series. Calculate the wavelength associated with an electron of a mass = 9.109 * 10^-28g that travels at 40% of the speed of light. Calculate the wavelength associated with a neutron having a mass of 1.675 * 10^-24 g and a kinetic energy of 6.21*10^-21J. (Recall that the kinetic energy of a moving particle is E = mv^2.)...
