The pupil of a cat’s eye narrows to a vertical slit of width 0.53 mm in daylight. Assume the average wavelength of the light is 498 nm. What is the maximum distance for which the cat can separate two mice in horizontal plane located at 9 cm from each other? (Give your answer in decimal with one digit after the decimal point, using "m" (meter) as unit.)
