A right-circularly polarized photon of the correct energy will promote an electron between states by changing l by ±1 and changing m by +1. Which of the following transitions are possible?
  1. (l=0, m=0) to (l=1, m=1)
  2. (l=2, m=0) to (l=1, m=0)
  3. (l=3, m=3) to (l=4, m=2)
  4. (l=0, m=2) to (l=1, m=3)
