Calculate its Period. WebMay 7, 2015 · Hydrogen. We can identify three bright lines for hydrogen in the top spectrum. Measuring from the scale, the wavelengths are 435 nm (purple), 486 nm (blue) and 657 nm (red). Recall (e.g. from the Calculation Investigation) that the the frequency is given by n = c / l , and the energy is given by E = hn (where h = 6.626 x 10 -34 J-s, and c = 3 x ...
