When an electron of an atom falls from a higher energy level to the ground state, the atom loses 9.4145 x 10-25 joules of energy. What is the wavelength of the radiation emitted as a result of this transition? (Planck's constant is 6.626 x 10-34 joule seconds; the speed of light is 2.998 x 108m/s) ?
