2. {2t} points} A horizontal glass sheet with Thickness Tand refractive index n = 1.62 is suspended in The air. It is illuminated lrom above. and you observe The reected light with your eye above The sheet. a.) [5 points} Draw a diagram showing The sheet. your eye1 and all The incident1 reected and transmitted rays you need to evaluate The intensity reaching your eye. Show all reection phase ips {if any}. h.) (5 points] Suppose that the incident light has a wavelength of 40G nm. Find the smallest nonzero thickness T of The glass such That no light reaches your eye. Discuss your reasoning in detail, andjustify all phase shifts. c.) 1' ll] points} Now suppose That The incident light consists of a mix of TWO wavelengths, 400 nm and TDD [1111. Again nd the smallest nonzero thickness Tol the glass such That no light of either wavelength reaches your eye.You should get a single answer [or Tinot two separate answers]
