Monochromatic light of wavelength, lambda, is traveling in air. The light then strikes a thin film having an index of refraction, n1 that is coating a material having an index of refraction n2. If n1 is larger than n2, what minumim film thickness will result in minimum reflection of this light?
A. lambda/(4*n2)
B. lambda/n2
C. lambda/4
D. lambda(2*n1)
E. lambda
F. lambda/(2*n2)
G. lambda/n1
H. lambda/(4n1)
I. lambda/2
