L7.2 Approximate WKB solutions

[@ehsanjabbar4563]

At 17:30 there should be a unit vector in the numerator as J is a vector, so that divergence of J also makes sense.

The difficult thing of wkb theory is when you have to connect the solutions in the forbidden zone to that in the classical. We have to approximate the potential in the reversal point and resolve schrodinger equation there. I never undestood how to use that solution to connect the wkb solution.

Absolutely well done and definitely keep it up!!! 👍👍👍👍👍

Thank you sir ☺️

At 7:42 he mistakenly said square root of rho instead of square root of p(x)--> momentum

Does anyone have this lecture written?or any other detailed solution of se with wkb approximation

[@denhafiz1860]

I think there are lectures notes linked in the description
