The mass of the particle in the infinite well is 2.00 × 10−30 kg, and the width of the well is 1.00 × 10−9 m. If the particle makes a transition from the third eigenstate to the second eigenstate, what will be the wavelength of the emitted light?

2. Relevant equations

E(emitted) = E(3) - E(2)

E(3) = 9h^2/8mD^2

E(2) = 4h^2/8mD^2

E(photon) = hc/lambda

3. The attempt at a solution

I thought this would require solution using the equations above and then use the energy found to calculate the photons wavelength. The only problem is I get weird units after working out the energy of the photon. I get the SI units to be J^2 s^2 kg^-1 m^-2. I would expect the units to cancel to just J. They dont so I assume im going wrong somewhere, is my approach correct? =S
