An oil slick on water is 80.5 nm thick and illuminated by white light incident perpendicular to its surface. What color does the oil appear (what is the most constructively reflected wavelength, in nanometers), given its index of refraction is 1.46? (Assume the index of refraction of water is 1.33.) wavelength nm color ---Select--- Select--- violet (1 = 410 nm) blue (1 = 470 nm) Additional Ma green (2 = 550 nm) yellow (1 = 580 nm) Reading orange (1 = 610 nm) red (1 = 660 nm) This wavelength is not visible.
