inal side of the surface AB. Thus, A, H, H, H, C,being the centres of the wavelets, we note first that thedistance AG must be traversed wholly after reflection fromA. We therefore describe from A the arc AN with radiusAG. The path CB, on the other hand, is wholly describedin the original direction… … BM m MG Fio. 25.—Plane Reflection on Huyghens Principle. then to be treated as the radius of a wavelet whose centreis K. We thus derive the plane wave front BN, reflectedfrom AB, as the envelope of arcs whose centres areA, K, K, K, and radii AG, KM, KM, KM respectively.The three pairs of lines,…
