Homework Statement the wavelengths of the emission lines produced by the hydrogen atom are given by the formula: 1/lambda = 1.096776 x 10^-2 ((1/n2^2) - (1/n1^2)) nm^-1 (a) what are the wavelengths of the first two lines in the Balmer series, H-alpha and H-beta (involving transitions...

how do you get lambda = h/mv i know E = hc/lambda = h/mv so, if i combine both equations, shouldn't i suppose to get lambda = cmv ? did i miss something or what.
