41. Photons of equal energy were incident on two different gas samples. One sample containing H atoms in the ground state and the other sample containing H atoms in the excited state with a principal quantum no. n. The photoelectric beams totally ionise the H atoms. If the difference in the kinetic energy is in the two different cases is 12.75 ev.Then find the principle quantum no. n of the excited state.
