Consider a thin film of thickness t = 2.30 × 10-6 m and index of refraction ng = 1.20. The film is rest- ing on a material of index of refraction ne = 1.13, and its top face is exposed to air na = 1.00. What is the shortest wavelength of visible light that will interfere destructively when incident on the film at angle Oa = 22.0° from the normal? Give your answer in nanometers, to three significant figures. [Note: you may ignore the fact that the wavelength will change upon refraction; this will only very slightly affect the answer.] na ne
