Webb2 Linear polarization We say a plane wave is linearly polarized if there is no phase diﬀerence between Ex and Ey. We can write linear polarizations as E~ 0 =(Ex,Ey,0) (8) and choose the overall phase so that Ex and Ey are real numbers. If Ey =0 but Ex =/ 0, we have E~ =E 0 xˆei(kz−ωt) (9) with E0 = E~0 just a number now.Then, from Eq.

WebbSo, comparing the two reflected rays, there is no component of the phase difference due to reflection: these effects cancel out. Let's consider a wavelength λ in air and so a wavelength λ glass in the glass. Now suppose that thickness of the layer is t = λ glass /4 = λ/4n. So the second reflected ray has travelled λ glass /2 further, so ...
