Please correct me if I am wrong but I don't think Shankar is wrong. He is discussing a general case(not specifically particle in a box) where V is infinite for x > L/2. Now time independent schrodinger says
ψ'' = [- 2 m(E-V)/hbar^2)]ψ.
So it is perfectly consistent mathematically that ψ''...
I was studying particle in a box from shankar and I couldn't get the following point. If V is infinite at for x > L/2 and x < L/2, so is double derivative of psi. Now Shankar mentions that it follows the derivative of psi has a finite jump. I am not able to get this point because according to my...
hi f2009567,
I am also in 2nd year in DCE(delhi college of engineering) in EEE branch and also stuck in a similar position as i don't have much interest in engg. and really like physics...I have tried to find out from various sources and i think we can get into a decent college offering MS in...
