When a particle with Energy $E>0$ approaches from $x<0$ an infinite negative potential with following conditions:
$ V(y)= \begin{cases} 0 &\text{if}\,& x\leq 0 \\ -\infty&\text{if}\,& x>0 \\ \end{cases} $
What is the probability its going to be refelcted?
So when I look at this my first Idea is that its goint to have $0$ probability of being refelcted because it would just gain infinite energy by passing the barrier. However my answer is wrong and it turns out it has a probability of $1$ to be reflected. Im not sure how this can be explained.
Quick edit to show my work:
$k_1=\sqrt{\frac{2m}{h^2}(E)}$
$k_2=\sqrt{\frac{2m}{h^2}(E-V_0)} = \sqrt{\frac{2m}{h^2}(E+\infty)} \rightarrow \infty$,
Transmission coefficient:
$T \propto \frac{k_2}{k_1} = \infty$ so there cant be any reflection.
