![(b) What is the general form of the solution to the Schroedinger Equation where a) E>U and b) E<U 2 marks] A particle is confined in a 1-D box of length L such that U=0 for 0〈x〈 and U is infinite elsewhere. Find an expression for the wavefunction inside the box which meets these boundary conditions, and show that it satisfies the Schroedinger equation. 2 marks] If the potential outside the box is Uo> O instead of infinite, describe with the aid of a sketch how the form of the lowest energy wavefunction changes.
