solve it correctly please. I will rate accordingly with multiple votes

A hydrogen atom in an excited state with principal quantum number n relaxes to a lower state by emitting a photon of wavelength A. For the question parts belowI use the given values of n and it to determine the largest possible magnitude of the orbital angular momentum of the atom after emission. Your units should be J s for the momentum. n = 5, 1'. =1255nm. E n : 3,}1: 558nm. n = 6,1 :1096nm. E n : 4,1 :18?9nm. E n = 4, .1 : 43?nm_ E
