Question 13: (6 points) White light is incident normally on a thin soap film (n = 1.36) suspended in air. What is the minimum thickness of the soap film that will constructively reflect light of wavelength 540 nm? What is the next minimum thickness of the soap film that will constructively reflect light of wavelength 540 nm?

Step 1

Step 1: We can use the formula for constructive interference in thin films, which is given by 2n*t = m*λ, where n is the refractive index of the film, t is the thickness of the film, m is the order of the interference, and λ is the wavelength of the light. Show more…
