The Potential Barrier, case E ≥ V₀
Now, with an algebraic expression for the transmission coefficient, we adjust energy values and observe what happens to the particle.
1. With E ≫ V₀ - particles dont feel effect of barrier.
2. For certain energy values, all the particles will get transmitted over. These values, called energy eigenvalues, coincides with that of the infinite square well potential showcasing the phenomena of resonance.
Notice that there are more than one way to achieve full transmission.
