A gas of hydrogen like atoms can absorb radiations of 68 eV. Consequently, the atoms emit radiations of
only three different wavelengths. All the wavelengths are equal or smaller than that of the absorbed
photon.The initial state of the gas atoms is:

Option: 1

n = 2


Option: 2

n = 4
 


Option: 3

n = 3


Option: 4

n = 5
