Here n … The Lyman series is a series of lines in the ultra-violet. Therefore, it cannot be observed from ground level since stratospheric, mesospheric and thermo-spheric constituents are able to absorb it completely. Lyman Series When an electron jumps from any of the higher states to the ground state or 1st state (n = 1), the series of spectral lines emitted lies in ultra-violet region and are called as Lyman Series. This is called the Balmer series. Calculate the frequency of the n 5 line in the Lyman series of hydrogen. Ultraviolet O Visible Infrared Radio O X-ray. Show transcribed image text. When the electron jumps from any of the outer orbits to the first orbit, the spectral lines emitted are in the ultraviolet region of the spectrum and they are said to form a series called Lyman series (Fig). According to Bohr’s model, Lyman series is displayed when electron transition takes place from higher energy states(n h =2,3,4,5,6,…) to n l =1 energy state. The Lyman series involve jumps to or from the ground state (n=1); the Balmer series (in which all the lines are in the visible region) corresponds to n=2, the Paschen series to n=3, the Brackett series to n=4, and the Pfund series to n=5.
