Solving the time-independent Schrödinger equation for a potential step

Homework Statement

Hi, I've just started this new course about quantum mechanics and it begins, among others, with this question:

I'm really at a loss how to approach this one. Can anyone please help?

Well, what do you know? How familiar are you with the Schrödinger equation, and the concepts of operators, eigenfunctions, and eigenvalues?

Thanks for trying to help :D
I know the definitions of those terms that you have mentioned; but, I am not familiar with their mathematical components enough to use them to tackle the problem freely.

You've got to make an effort here if you want us to help you, schnuffi.

Suppose this were a problem on an exam. How would you start? Go back to your references (textbook, notes, etc.) and look things up, if you have to.
