Question 2 0 / 2.5 pts How many different types of waves and the number of degeneracy of each at the second energy level for a plane stationary wave analogous to the harmonic vibrations of a drum and the energy levels in planar molecules/moieties? 3 types; one is non-degenerate, one is doubly degenerate, and the third is triply degenerate. 2 types: one is doubly degenerate and the other is triply degenerate. 2 types: one is doubly degenerate 1 type: doubly degenerate 2 types: one is triply degenerate. Can someone explain what the right answer is and how to get it, the first one is wrong
