Thin Film Interference and Refractive Index
A thin film of benzene (n = 1.50) with a thickness of 75 nm rests on a surface. When white light illuminates the film, blue light (λ = 450 nm) is absent in the reflected light. What is the index of refraction of the surface?
A
Exactly 1.00
B
Greater than 1.50
C
Less than 1.50
D
Cannot be determined from the information given
