A point source is placed at co-ordinates \((0,1)\) in \(X-Y\) plane. A ray of light from the source is reflected on a plane mirror placed along the X-axis and perpendicular to the X-Y plane. The reflected ray passes through the point \((3,3)\). What is the path length of the ray from \((0,1)\) to \((3,3)\) ?
