Paiye sabhi sawalon ka Video solution sirf photo khinch kar. Notice that the lines get closer and closer together as the frequency increases. Wavelength of the first line of balmer seris is 600 nm. 0 votes . Basically, as Mia said, use the Lyman series in the Rydberg equation when n1 is 1, and the Balmer series when n1 is 2. Try this, The Lyman Series say the for the second is 121.6nm (nano metres) For the third it is 102.6 and the fourth is 97.3 all in Nano Metres which *10^-9. I don't believe that the Balmer series with n1=2 means that the electrons are starting in their ground state, or else it would be equal to 1. The second transition in the Paschen series corresponds to. what is the wave length of the first line of lyman series ? ∴ Wavelength of second line of Lyman series is 102.5 nm. The wavelength (in cm) of second line in the Lyman series of hydrogen atomic spectrum is (Rydberg constant = R cm − 1) 8.
