    2021-6-15 · Fresnel's law of reflection states that the fraction of light reflected for normal incidence is: r = (n-1) 2 (n+1) 2, where n is the ratio of the refractive indexes of the two media. If n = 1.5 for air and glass, then r = 4% for each surface. Two filters separated by air transmit 8% less than two connected by optical cement (or even water).
