A technician places a fluid substance, with a refractive index of 1.75, between two horizontal panes of flat glass (each of which has n = 1.40). He then illuminates the assembly from above with monochromatic light (? = 550 nm). What is the minimum thickness (in nm) that the liquid layer must have if the light is to be strongly reflected back toward its source?
