  1. A thin layer of a material with an index of refraction 1.50 is placed on top of a translucent slab with an index of refraction of 1.80. Air surrounds both. When a source of white light is shown on the surface, the top layer greatly reduces the intensity of reflected light having a 630-nm wavelength. (a) Find the top layer’s minimum thickness. (b) Does it reduce other reflected wavelengths in the visible spectrum? Which ones? (c) If 25.0nm were shaved off of the top layer, which reflected wavelengths in the visible spectrum are suppressed?

A thin film in air is made by putting a thin layer of acetone (n = 1.25) on a layer of water (n = 1.33). When visible light (400nm – 700 nm) shines normally on the film an observed from above, the bright reflected light looks kind of “purplish” with red light of wavelength 650 nm mixed some blue giving it that appearance and “greenish” light of wavelength 520 nm is completely destroyed. Determine the thickness of the acetone film....

A thin layer of transparent oil is placed on top of a transparent plate. The oil film is then illuminated by white light shining onto the oil's surface, as shown in the figure above. To an observer standing right next to the light source and looking straight down on the oil film, the oil film appears green, corresponding to a wavelength of 528 nm in air. The oil has an index of refraction of 1.52. Part (A) What is the...
