9. Light from a discharge tube containing H-
atoms in some excited state, falls on the
metallic surface of metal Na. The KE of the
fastest photo-electron was found to be
10.93eV. If He ions were present in the
same excited state, the KE of the fastest
photo-electron would have been 49.18 eV.
Determine the excited state orbit number
and work function of Na.
A) 2,18.2 ev
B) 4,1.82 ev
C) 3,16 ev
D) 2,1.6 ev
