In an experiment, olive oil (n=1.47) is added to a glass of water (n=1.33) slowly to form a thin film on top of the water. When the film appears to be dark under a red light (=685 nm) for the first time, no further addition of the oil is made. What color, measured in wavelength, will the film appear to be if the glass is directly under the sun light?
