Physics - Ch 66 Ch 4 Quantum Mechanics: Schrodinger Eqn (32 of 92) Finite Potential Well Part 1

In this video I will explain the particle in a finite well instead of an infinite well. Which means the barriers does not have infinite height or energy. In quantum mechanics that means the particle can venture outside of the trapped region. For example if region 1 is the barrier on the left-side, region 3 is the barrier on the right-side, and region 2 is in the middle where the particle is located, and if the barrier is infinite in height that means it'll require an infinite amount of energy for the particle to cross the barrier into regions 1 and 3. However if the energy required to cross into regions 1and 3 is finite, then the particle can reside in region 1 or 3. (Part 1)

Thank you for uploading so many videos every day I love your enthusiasm and all your videos are conceptually not compromising so thank you and continue your dedication!!

[nicholasmartin]

The bow tie gives all of the credibility.

Also, isn't the hbar is square in the denominator in the alpha term?
BTW thank you so much for such beautiful work!!

Its so sad that I'm a finite quantity... might stop chasing my dreams

[richieovandorincon]

So can we say for a finite well the potential energy inside the well is zero and outside the well it will be some constant and outside the well the wave function doesn’t equal zero?

[adosar]

Does any force exist in this potential well ? Both inside and outside the well the derivative of potential energy with respect to position is 0 therefore zero force. So what is the point to have 2 different potentials ?

Why does our D approach negative infinity =0 and why don't we do this for C as well?

[TheTck]

If the particle with energy E<U is measured in region 1 or 3, is the energy still less than the potential? I’m a bit confused how the energy is conserved when the particle tunnels into a region with higher potential.

[mehmetalivat]

Thank you. Could you solve spherical potential barrier?

Why potential energy of particle inside well is zero
