how to calculate the wavelength in nm for 5he four visible transitions and make sure the theoretical value consists with the experimental value and color

Answer 1

For atomic spectra of hydrogen, Balmer series is in visible o range weirelength ŚRC ) For Balmer series n = 2 - 12 = 3,4,5 R = Rydberg constant = 1.09678 x107 mi! 2 1 - = 1:09678 xlo - nm SO, Fo», ni = 2, 2 3 ( 3 + 2) Ś = 1.09678 xlo? monell ) os, 5 = 1.09678x?o?om (4-5) os, 17,- 658.46 nm =) Red color | Fos.
