An electron in a hydrogen atom makes a transition from the n=1 state to the n=3 state  (1eV= 1.6 x10^-19 J and h = 6.63 x 10^-34 J s= 4.136 x 10^-15 Ev/hz c =3.0 x10^8 m/s)    what is the energy of the photon absorbed in transition and what is the frequency of the absorbed photon energy?

An electron in a hydrogen atom makes a transition from the fifth excited state to n = 2.What are the frequency and wavelength of the emitted photon? (h = 4.136 x 10 -15 eV/Hz = 6.63 x 10 -34 J.s, c = 3.0 x 10 8 m/s, 1eV = 1.6 x 10 -19 J)

A mercury atom emits light at many wavelengths, two of which are at (1) 404.7 nm and (2) 435.8 nm . Both of these transitions are to the same final state. Determine the energy of each emitted wavelength (in J). A E1 = 7.908 x 10-19 J and E2 = 6.558 x10-19 J E1 = 4.628 x 10-19 J and E2 = 4.968 x10-19 J E1 = 5.908 x 10-19 J and E2 = 5.558 x10-19J E1 = 4.908 x 10-19 J and E2 = 4.558 x10-19 J
