## Homework Statement

I have an attachment

## Homework Equations

Schrödinger equation

## The Attempt at a Solution

The issues I am having is how to start this one. This is not a infinite square well but a semi-infinite square well.

I know that energy= K^2= 2mE/h^2

Where h is planks constant 6.626 X 10^-34 J•s

So rearranging (K^2 • h^2)/(2m) =E

How do I find my m and solve the other ones

At X=L

The first derivatives must be equal at X=L

Asin(kL)=Ce^(-aL)

KAcos(kL)=-aCe^(-aL)

Am I going in the right direction
