To understand just how this happens, take into consideration (Figure). Two rays arise from suggest P, win the mirror, and also reflect right into the observer’s eye. Note that we use the legislation of enjoy to build the reflect rays. If the reflected rays are expanded backward behind the mirror (see dashed currently in (Figure)), castle seem to originate from allude Q. This is where the picture of point P is located. If us repeat this process for point
