The energy difference between states A and B is twice the energy difference between states B and C (C B A). In a transition (quantum jump) from C to B, an electron emits a photon of wavelength 600 nm.

Question

The energy difference between states A and B is twice the energy difference between states B and C (C > B > A). In a transition (quantum jump) from C to B, an electron emits a photon of wavelength 600 nm.
