Question

Follow these steps to solve this problem: A very thin oil film (noil=1.25) floats on water (nwater=1.33). What is the thinnest film that produces a strong reflection for green light with a wavelength of 500 nm?

1.Which of the following equations should be used to find the minimum thickness t of the oil film that satisfies the conditions of the problem? Let be the wavelength of light in air and n the index of refraction of the thin film

. a. 2t=mn(m=0,1,2,...) for constructive interference.

b.2t=(m+12)n(m=0,1,2,...) for destructive interference.

c.2t=(m+12)n(m=0,1,2,...) for constructive interference.

d. 2t=mn(m=0,1,2,...) for destructive interference.

2. What is the minimum (non-zero) thickness t of the film that produces a strong reflection for green light with a wavelength of 500 nm?
