Physics

Monochromatic light of wavelength, λ 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 n2 is larger than n1, what minimum film thickness will result in maximum reflection of this light?

A λ/n1
B λ/2
C λ/(2n1)
D λ/n2
E λ
F λ/4
G λ/(4n2)
H λ/(2n2)
I λ/(4n1)
J The correct response is not shown above.
