Ok, so I'm back with more doubts about the applications of Fresnel equations and optics in general, if you don't mind helping me again.
Imagine a ray of light incident on a dielectric slab, such that the reflected light has intensity Ir=R*I_0 and the transmitted one It=T*I_0, being R and T...
Thanks to your explanation, Dickfore, I've discovered where I was wrong.
I was assuming that the Intensity was proportional to the amplitude of the electric field squared, and did not foresee that such proportion would change from one medium to another. So I just happily assumed T=(Et/E0)^2...
I'm quite sure it is. In any case, would you be so kind as to present any evidence to the contrary?
Please keep in mind I'm not talking about the ratio of intensities, but the electric field ratio.
Hi, I was wondering how come I can get a transmission coefficient higher than one?
In the equation at normal incidence:
t = E_t/E_0 = 2*n2/(n1+n2) > 1 if n2 > n1
How is it even possible to get a higher electric field amplitude out compared to the one that got in?
I'd be very...
