Homework Help: Schrodinger equation and hydrogen atom

  1. Mar 17, 2010 #1
    1. The problem statement, all variables and given/known data
    Find the width L of a one-dimensional box for which n=5 level would correspond to the absolute value of the n=3 state of a hydrogen atom

    2. Relevant equations
    am i suppose to use n2h2/8mL2 where n=5 to equate it to the n=3 state of the hydrogen atom? which is -13.6eV/32?

    3. The attempt at a solution

    i am confuse. or am i suppose to be using some other equations? i don't really understand the question though. appreciate any help

    You have to use these equations. Omit the signs, the absolute values have to be equal. m is the mass of the electron, and convert eV to joule.
