40. The situation is analogous to that treated in Sample Problem 36-5, in the sense that the incident light is in a low index medium, the thin flm oF oil has somewhat higher n = n 2 , and the last layer (the glass plate) has the highest reFractive index. To see very little or no reflection, according to the Sample Problem, the condition 2 L = µ m + 1 2 λ n 2 where m =0 , 1
