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 ... WebbWhen the average phase shift equals pi/2, the differential reflection phase shift delta is maximum, and the reflection Jones matrix assumes a simple form. For N > square root 3, the average and differential phase shifts are equal (hence deltap = 3 deltas) at a certain angle phi that is determined as a function of N. fishbowl gpu testWebb25 apr. 2003 · Δy = y m+1 - y m = (m + 1) λL/a - m λL/a = λL/a. Since the width of the central maximum = the distance between the first minimum on the right and the first minimum on the left of the central maximum, the width of the central maximum = 2 λL/a.
