Antireflection Coating A glass lens ( n glass = 1 52) has an antirefiection coating of MgF 2 ( n = 1 38). (a) For 545-nm light, what minimum thickness of MgF 2 will cause the reflected rays R z and R 4 in Figure 28-50 to interfere destructively, assuming normal incidence? (b) Interference will also occur between the forward-moving rays R 1 and R 3 in Figure 28-50. What minimum thickness of MgF 2 will cause these two rays to interfere constructively? Incident light.
