An oil slick on water is 144 nm thick and illuminated by light of all wavelengths incident at a 30° angle to the normal of the surface of the oil. What is the largest, most constructively reflected wavelength (in nm), given that the oil's index of refraction is 1.42? (Assume the index of refraction of water is 1.33.) 708.31 x nm What color does this wavelength correspond to? O violet (A = 410 nm) blue (A 470 nm) O green (A = 550 nm) yellow (A = 580 nm) orange (A = 610 nm) O red (A 660 nm) This wavelength is not visible.
