Most probable position of electron in an infinitely deep square well

  1. Dec 9, 2013 #1
    1. The problem statement, all variables and given/known data

    An electron in an infinitely deep square well has a wave function that is given by

    What are the most probable positions of the electron?


    3. The attempt at a solution


    I got the values as L/6, L/2, 5L/6 by finding the x values that made the wave function squared max( so the values that made the sin term=1)


    But the solution says L/4, L/2 and 3L/4 ?



    thanks

    Your answer looks correct to me. The answer given as the solution (L/4, L/2, 3L/4) is incorrect.
