Q2. An American standard analog television picture (non-HDTV), also called as NTSC, is composed of approximately 495 horizontal lines of varying light intensity. Assume your ability to resolve the lines is limited only by the Rayleigh criterion, pupils of your eyes are 4.80 mm in diameter, and an average wavelength of the light coming from the screen is 560 nm. Compute the ratio of the minimum viewing distance to the vertical dimension of picture such that you would not be able to resolve the lines.
