Physics - Ch 66 Ch 4 Quantum Mechanics: Schrodinger Eqn (75 of 92) Penetration Depth V0, E

In this video I will find the wave function and the magnitude of the wave-function square=? where a particle with energy E comes upon a step with a potential V0 where V0 greater than E. Or, where the energy of the particle is less than the potential of the step.

Next video in this series can be seen at:

may i ask why the |2root0.1/root0.1+i root 0.9|^2 is =4(0.1)/root(1),
where is the i....isnt that use the expansion (a+b)^2?

why should be an instant decay when the particle penetrate the well ? why it dosen't go up then decays till it reaches zero?

I'm not sure whether you can separate the sqrt(-1) from the formula and denote it as i. imaginary unit is defined via the relation i^2 = -1, which implies two roots for i, +-sqrt(-1). How do you justify your selection?

Thanks for saving me from failing all the time :)
