The pupil of a cat's eye narrows to a slit of width 0.7 mm in daylight.Assuming a wavelength of 500 nm,what is the angular resolution? (1 nm = 10^-9m) A)0.7 x 10^-3 rad B)6 x 10^-3 rad C)0.7 x 10^-4 rad D)6 x 10^-4rad

Question

Angular resolution is given by the ratio of wavelength to the slit width. So, angular resolution = (500 x 10^-9 m) / (0.7 x 10^-3 m) = 0.7 x 10^-3 rad.
