The equations for R and T in the E > U0 barrier are essentially the same as for light passing through a transparent film. It is possible to fabricate a thin film that reflects no light? Is it possible to fabricate one that transmits no light?
Why or why not?
Let me type the exact q ...
A beam of particles of energy E and incident upon a potential step of U0 = 3/4 E is described bby the wae funciton
Y(x) = 1 e^(ikx)
The amplitude of the wave (related to the number incident per unit distance) is arbitrarily chosen as unity.
