Calculate the wavelength of light required to make a transition from n=1 -> n=2 and from n=2 -> n=3.?

Part A) Calculate the energies of the n = 1, n = 2, and n = 3 levels for an electron in a box with a length of 305 pm.Enter your answers separated by a comma. I did that, the answers are:E_1, E_2, E_3 = 6.48×10^−19, 2.59×10^−18, 5.83×10^−18 JPart B) Calculate the wavelength of light required to make a transition from n=1 -> n=2 and from n=2 -> n=3.?Enter your answers separated by a comma. This part I don't understand.

delta-E = hc/lambda, where h = Planck's constant and c = speed of light. That tells you the wavelength corresponding to an energy change of delta-E.Rearranging, lambda = hc/delta-E.So calculate the energy difference between n=1 and n=2. Plug that delta-E into the equation and solve for lambda. That's the wavelength corresponding to that energy change.Do the same for the energy difference between n=2 and n=3.... Show More
