Question

The electron, in a hydrogen atom, initially in a state of quantum number n1 makes a transition to a state whose
excitation energy, with respect to the ground state, is 10.2 eV. If the wavelength, associated with the photon
emitted in this transition, is 487.5 nm, find the (1) energy in eV, and (ii) value of the quantum number, n1 of the
electron in its initial state.​
