For the tunnel-effect, the relation between the transmissioncoefficent T and length of the barriere L is:
[itex]T=e^{-2KL}[/itex]
in which:
[itex]K=\sqrt{\frac{2m(U_0-E)}{\frac{h}{2\pi}^2}}[/itex]
Now, the tunnel-effect is possible for light right? But light means m=0, meaning K=0, meaningT=1!
I must be missing the point somewhere but I can't figure out where
