75. Consider the interference pattern formed by waves reflected from the upper and lower surfaces of the air wedge. The wave reflected from the lower surface undergoes a π rad phase change while the wave reflected from the upper surface does not. At a place where the thickness of the wedge is d , the condition for a maximum in intensity is 2 1 2 dm =+ b g λ, where λ is the wavelength in air and m is an integer. Therefore, d = (2 m + 1) λ /4. As the geometry of Fig. 35-47 shows, dR R r =− 22
