Electron transition from n ≥ 4 n\ge4 n ≥ 4 to n = 3 n=3 n = 3 gives infrared, and this is referred to as the Paschen series. So the smallest amount of energy will be transmitted when an excited electron fall from n=4 to n=3. Members of a homologous series are called homolog. The Lyman series lies in the ultraviolet, whereas the Paschen, Brackett, and Pfund series lie in the infrared. The transitions: from n = 4 to n = 3 is called Paschen-alpha, from n = 5 to n = 3 is Paschen-beta, 6 to 3 is Paschen … In the Paschen series all electron movement is from higher levels to the n=3 level. The shortest wavelength in Paschen Series is therefore 818 nm. This is the only series of lines in the electromagnetic spectrum that lies in the visible region. ��zG��!��v��(�ZU��u�aYۃ� D��ٞ`Y�8�/�h� ��`��`��`�>0�̮�� `[�Ad�4�d��H�H�D��Ԙ� ��'��?�K� �� Physics. For example the Lyman series (nf = 1 in Balmer-Rydberg equation) occurs in the ultraviolet region while the Balmer (nf = 2) series occurs in the visible range and the Paschen (nf = 3), Brackett (nf = 4) and Pfund ( nf = 5) series all occur in the infrared range. You can plug in the Rydberg constant and the values n=4 and n=3 into the Rydberg equation to find the wavelength. �B��)t (a) Lyman series is a continuous spectrum (b) Paschen series is a line spectrum in the infrared (c) Balmer series is a line spectrum in the ultraviolet (d) The spectral series formula can be derived from the Rutherford model of the hydrogen atom 2 Rydberg formula; 3 Series.
