2) (Diffraction limit of human eye) (Adapted from a problem by Prof. Walter Smith.) Let's see how the resolution limit for the human eye due to diffraction from a circular aperture (the pupil) compares to that required to see things on computer screens and high-def TVs. Assume that the wavelength of light is 550 nm on average, and that the pupil of the eye has a diameter of 4.00 mm. a) How does the angle subtended by a single picture...
