Question

1. determine which emission has the highest energy and which has the lowest energy

2. determine which absorption has the longest wave length and which has the shotest

Answer 1

longest path = highest energy transition = shortest wavelength

shortest path = lowest energy transition = longest wavelength


also, remember that the "spacing" between orbits gets smaller as you go outwards.

that is n=1 to n=2 is a more energetic transition than n=2 to n=3
