Perhaps the most common scenario for mirroring is in computer graphics. The reflecting line's slope is the delta from its slope to the slope of the x axis. If multiple incident rays parallel to each other reach a smooth surface, such as still water, the reflected rays are all bounced off at the . For example, when point P with coordinates (5,4) is reflecting across the Y axis and mapped onto point P', the coordinates of P' are (-5,4). The input reflection coefficient angle will be decreased by twice the electrical length of the line Θ L − 2 β l. On Smith Chart, decreasing the phase of the reflection coefficient means going clockwise on the SWR circle. The new graph is a reflection of the original graph about the x-axis.
