    1. The problem statement, all variables and given/known data


    2. Relevant equations
    See below.

    3. The attempt at a solution
    This is only a 1 mark question so I'm probably missing something really simple but I just cant figure it. Below is the slide we have been given:


    Does anyone have any ideas?

    Thanks for the post! This is an automated courtesy bump. Sorry you aren't generating responses at the moment. Do you have any further information, come to any new conclusions or is it possible to reword the post?

    It should be ~1V so the square potential is not deformed and the probability increase due to curved edges of the potential.

    Not that it matters, the exam had nothing on this question or anything else I studied.
