A disabled tanker leaks kerosene (n = 1.20) into thePersian Gulf, creating a large slick on top of the water(n = 1.30). (a) If you are looking straight down from an airplane, while the Sun is overhead, what is the thickness at a region of the slick where the reflection is brightest for visible light with wavelength 488 nm? (b) If you are scuba diving directly the slick,what is the thickness for which light with wavelength 583 nm is transmitted strongest?
