(b) A soap film has an index of refraction n = 1.33. Light of wavelength λ = 500 nm is incident normally on the film. Calculate i. smallest thickness of the film that will give a maximum interference in the reflected light. ii. maximum interference if doubling the thickness of the film calculated in part i. (3 marks) (c) A light source emits visible light of two wavelengths (λ = 430 nm and 2 = 510 nm). The source is used in a double-slit interference experiment in which L = 1.50 m and d = 0.025 mm. Find the separation distance between the third-order bright fringes.
