The distance between the atoms in a Silicon crystal is a = 2.35 Angstrom = 2.35 x 10-10 m. How much larger is the wavelength of visible light with a frequency of f = 5.63 x 1014 Hz? Give the ratio of the wavelength to the atomic distance. Note: this is the reason why atoms can not be seen by an optical microscope. Part 3) Air 0 Oil Water Figure: The distance d is the horizontal distance between the location the ray refracted in the oil meets the water and where a ray that was not refracted by the oil (ie. kept traveling along a straight line path) would meet the water. A thin, 1.00 mm thick, film of oil is floating on top of water. The oil film has a thickness of 1mm and the index of refraction of oil is now = 1.46 The index of refraction of water is nwater = 1.33. A ray of light is entering the oil surface from air (nair = 1.00) at an angle of 0 = 12.2" with respect to the normal. What is the final angle of the ray of light in water with respect to the normal? Owater What is the displacement d caused by the 1.00 mm thick oil film (see the Figure)? mm
