The second expression is correct. I used "a" for the width of the square well, whereas you used "L."

The Schrodinger equation is a "eigenvalue" equation. E is the energy eigenvalue for a particle in a state with "n" equal to some (quantized) number.

How can you not know what hbar is?? hbar is defined as Planck's constant divided by 2 pi.

How can you even ask these questions? You had to solve the Schrodinger equation to get to this point!
