To understand just how this happens, consider (Figure). 2 rays arise from point P, win the mirror, and reflect into the observer’s eye. Note that we use the regulation of enjoy to build the reflected rays. If the reflected rays are expanded backward behind the mirror (see dashed present in (Figure)), they seem to originate from allude Q. This is where the image of suggest P is located. If we repeat this procedure for allude
