1.	In an experiment on photoelectric effect photons of wavelength 300 nm eject electrons from a metal of work function 2.25 eV. A photon of energy equal to that of the most energetic electron corresponds to the following transition in the hydrogen atom:
A.	n = 2 to n = 1 state.
B.	n = 3 to n = 1 state.
C.	n = 3 to n = 2 state.
D.	n = 4 to n = 3 state.
Answer» D. n = 4 to n = 3 state.
