Q13 of 106 Page 384

Whenever a photon is emitted by hydrogen in Balmer series, it is followed by another photon in Lyman series. What wavelength does this latter photon correspond to?

It is said that the photon is emitted in Balmer series and then next in Lyman series. Balmer series correspond to n=2 state and Lyman series corresponds to n=1 state. If we take n=1 and m=2, then we obtain the wavelength as,
