Think of an image as a screen-door, with each square in the screen being a pixel. This is then the object the eye sees through that pixel.

In optics, a ray is an idealized geometrical model of light or other electromagnetic radiation, obtained by choosing a curve that is perpendicular to the wavefronts of the actual light, and that points in the direction of energy flow. [ 1][ 2] Rays are used to model the propagation of light through an optical ...
