A Particle energy A trapped in infinite square well. U(x)=0 for 0<x<L and U(x)=U0 for L<x<2L. find the wave function of the particle when A) E>U0 B) E<U0 C) E=U0.
2. Relevant equations
1-D time independent Schrodinger equation.
3. The attempt at a solution
I have the correct wavefunctions for the particle from 0<x<L and L<x<2L ,(have checked solutions) however I dont understand how to write join them together into one function.
any help would be appreciated, I am new to this subject so please go easy on me haha.
thanks in advance,
