A standard 14.6-inch or .360 meter computer monitor is 1024 pixels wide and 768 pixels tall. Each pixel is a square approximately 281 micrometers on each side.
If the maximum distance between the screen and your eyes at which you can just barely resolve two adjacent pixels is 1.30 meters, what is the effective diameter of your pupil? Assume that the resolvability is diffraction-limited. Furthermore, use 550 nanometers as a characteristic optical wavelength.
