okay so i need some help interpreting some of the results,
so (-ħ2/2m)Ψ''=E-V0Ψ;
So i set k2= 2m*(E-V0)/ħ2
and so : Ψ''=-k2Ψ
so if V0=0 or is smaller than E, k2 is positive;
*need for help starts here*
Ψ=Aeikx+Be-ikx;
another result for this would also be only eikx so is the second term only there to represent the possibility of the wave to travel in both directions?
now for the trignometric result is the same, are both the sines and cosines there to represent both directions?
ok so when V0 is bigger than E i can just set k2=-2m*(E-V0)/ħ2 and so
Ψ=Aekx+Be-kx
there is no trig result correct?
