Consider three electron jumps described below for the hydrogen atom
`{:["X: n=3 to n=1"],["Y: n=4 to n=2"],["Z: n=5 to n=3"]:}`
(a) The photon emited in which trasition ` X, Y` or (Z) will have shortest wavelength ?
(b) For which transition will the electron experience the longest charge in robit radius ?

Explanation

(a) `X` (b) `Z`
