A disabled tanker leaks kerosene (n = 1.20) into the Persian 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, at a region of the slick where its thickness is 430 nm, for which wavelength(s) of visible light is the reflection brightest as of constructive interference?
b) If you are scuba diving directly under this similar region of the slick, for which wavelength(s) of visible light is the transmitted intensity strongest?
