USE A = 6, B = 6. The pupil of a cat's eye narrows to a vertical slit of width a = (A + 1.0) × 10⁻⁴ m (meters) in daylight conditions. Assume an average wavelength of light to be λ = (425 + B) nm (nanometers). What is the angular resolution for the cat to just make out the presence of 2 mice versus just seeing one? Give your answer in radians and with 2 significant figures.
