WebHydrogen spectrum wavelength. The Balmer series requires that nf = 2. The first line in the series is taken to be for ni = 3, and so the second would have ni = 4. The calculation is a straightforward application of the wavelength equation. Entering the determined values for nf … WebI was seeing the proof of the de broglie wavelength. He equated E=mc^2 and E=hf. Then, hf=mc^2 If I'm not crossing a line, if we separate the constants to one side and the variables to the other, we get: f/m=c^2/h which is a constant. What does that even mean? Is f/m always a constant? #Sorry to have posted this doubt again. :-) • ( 4 votes)
