Answer 1

Answer #1

When the hydrogen atom is excited to 3D state it emits two photons while coming back from M shell to L shell and then from L shell to K shell

Energy of M shell of hydrogen atom is -1.51 electron volt

Energy of L shell of hydrogen atom is -3.40 electron volt

Energy of K shell of hydrogen atom is -13.6 electron volt

So first photon coming from M shell to array shell will have energy of 1.89 electron volt

Second Photon coming from L shell to K shell will have energy of 10.2 electro volt.
