1. Write the Schrodinger equation for particle on a ring, and
rearrange it until you have the following: ? 2? ??2 = − 2?? ℏ 2 ?
…
a) Assuming that ?? 2 = 2?? ℏ 2 , (where ml is a quantum number
and has nothing to do with mass), show that the following is a
solution for the Schrodinger equation you obtained: ?(?) = ? ?
