In a hydrogen like sample electron is in 2nd excited state the Binding energy of 4th state of this sample is 13 6 then A A 25 eV photon can set free the electron from the second excited state of this sample B 3 different types of photon will be observed if electrons make transition up to ground state from the sec excited state C If 23 eV photon is used then K E of the ejected electron is 1 eV D 2nd line of Balmer series of this sample has same energy value as 1st excitation energy of H atoms
