PHYS 110B - HW #5
... Our solution is sin θT = 0. For transmission we limit the angle to 0 ≤ θT ≥ π/2 (if the angle was greater than π/2 then the wave would be propagating back through the glass instead of being transmitted). This means that we have shown θT = 0. Now, going back to either (42) or (44) and considering tha ...
