... If we now consider the refracted beam, we know that it travels under an angle β, has the same frequency as the incident beam, but a wavelength λd and a velocity c that is different from λi and c0. Moreover, we must expect that it is damped or attenuated, i.e. that its amplitude decreases as a functi ...
