QM2.2: Potential Step E ≥ V₀ - Description of Plane Waves

[WoAiJesu]

shouldn't it be R= (|B|^2)/(|A|^2), where J_refl = B and J_in = A. Then |A|^2 and |B|^2 will be the probabillity density, right?

He didn't write it wrong at 0:55.

Because of the fact that he drew the plane wave towards the left, it account for the negative within the exponential factor.

a little correction: He forgot a minus in front of k in the exponent of B at 0:55. Actually something that is obvious, but good to point out to avoid confusion.
