A puddle of water (n=1.33) is covered with a very thin layer of oil( n=1.10). A green light of wavelength 550nm in air is incident onthe oil surface at an angle near 0o relative to the linedrawn perpendicular to the surface of the oil.
a) what is the speed of light in the water?
b) In a region of the surface that minimizes the reflection of thislight, how thick is the oil film? Begin by drawing a ray diagram(required) that shows schematically, the light reflection ofrefraction as it interacts at the air-oil and oil-water boundaries.
