A researcher measures the thickness of a layer of benzene (n = 1.50) floating on water by shining monochromatic light onto the film and varying the wavelength of the light. She finds that light of wavelength 590 nmnm is reflected most strongly from the film. What does she calculate for the minimum thickness of the film? Express your answer with the appropriate units.
