** 38. Two plastic plates (index of refraction n = 1.3) are separated by an air gap of 0.9 µm.Analyze the reflections of light of wavelength 600 nm and conclude whether it will be brightlyreflected or not.0.9 um gap<>** 39. The air gap in the previous problem is now filled with a mineral oil whose index ofrefraction is n = 1.5. Analyze the reflections of light of wavelength 600 nm and conclude if itwill be brightly reflected or not.

There are 2 different questions. As per our policy, we will answer the first one. Kindly resubmit…
