Question
The Balmer series corresponds to emission spectral lines from hydrogen-like atoms transitioning from higher energy state to n = 2. a) Calculate the wavelength of the third line of the Balmer series for Li2+. b) The photon from part a) is used to strike the surface of zinc, the work function of which is 6.82 × 10-19 Calculate the maximum speed of the photoelectron. c) Calculate the de Broglie wavelength of the photoelectron from part b). d) Can you observe the wave from part c) with a diffraction grating with a spacing of 1 um? Why or why not?
