1. The problem statement, all variables and given/known data An electron confined in a one-dimensional box is observed, at different times, to have energies of 27 eV , 48 eV , and 75 eV . What is the length of the box? Hint: Assume that the quantum numbers of these energy levels are less than 10. 2. Relevant equations E=h^2n^2/(8mL^2) 3. The attempt at a solution I tried using that equation to solve for length, but I dont know what energy levels these are at, so i cant seem to solve it.
