1. What are the longest and shortest wavelengths emitted from a fictitious hydrogen atom that end on the n = 1 state if the energy at this state was actually 54.4 e V? 2. a) Calculate the wavelength of an electron (m = 9.1 x 10 3kg) traveling at a speed of 1 x 10 m/s. b) Does a proton or electron beam have a larger spaced pattern in a double slit experiment
