Hi,
I an reading an interesting chapter of Feyman where he explains the basis of light-matter interaction with wave theory: http://cua.mit.edu/8.421_S08/Reading...refr_index.pdf
I didn't understand there one thing... to explain it he says that all the dipoles on the plate ''feel'' the same electric field with the same phase [page 4, equation 31.10]. to say this the plate has to be very very very thin [something like 0.1 of the wavelength]... how this can be practical??
