A ground state hydrogen atom absorbs a photon of light having a wavelength of 92.05 nm. It then gives off a photon having a wavelength of 901.3 nm. What is the final state of the hydrogen atom?
Answer:- n=1 at wavelength 92.05nm
An electron is transferred to level 10 when n=10 (n2 = sqrt (Rl/Rl – 1) = 10);
Transferring an electron from the tenth level to level three at a wavelength of 901.3 nm (n1 = sqrt (100 X Rl/(100 + Rl)) = 3).
The ultimate state of the atom is n=3.
