What happens if we re-excite an excited electron to a higher energy level? e.g. we excite hydrogen's electron from n=1 to n=3, then before it gets to return to the ground state, we hit it with another photon with the right frequency to move it to n=6:
1- is this even possible?
2- How does the electron releases it's energy and return to ground state?
A. will it release all of its energy as a single photon and return from n=6 to ground state in one step?
B. or it will first release a photon with the same frequency as the last photon it absorbed and return from n=6 to n=3, then release another photon and return from n=3 to n=1?
C. or it will return from n=6 to n=5 and release one photon, then from n=5 to n=4 and release another photon and so on?
