Determine “h’ by fitting data to Planck’s Formula: (A) (arbitrary units) pr The visible spectrum of the H atom: one proton + one electron These are the Balmer “lines” in the visible spectrum of excited H. What does any of this have to do with BALMER?  who was Balmer?  what did he do?  what happened then? Along come Einstein and de Broglie  Einstein explains Planck’s “ansatz” ε(ν) = n (hν)….  de Broglie suggests that if waves (e.g. light) might “be” particles, then (fair is fair) particles should also “be” waves! Wave-particle duality “X-rays”, and “electrons” diffracting through Al foil.
