Problem- Part 1) Calculate the wavelengths (in nm) of the visible lines in the line spectrum of hydrogen using the Rydberg equation (nf = 2; ni = 3, 4, 5, and 6).
Express your answers to three significant figures and order from shortest to longest wavelength
Part 2) Using Rydbergâ€TMs equation, determine the wavelength of the lines where ni =3 and nf=2. (RH = 1.097 x 107 m-1)
