Two rays of light converge toward each other, as shown in the figure, forming an angle of = 28°. Before they intersect, they are reflected from a circular plane mirror with a diameter of D = 12 cm. If the mirror can be moved horizontally to the left or right, Find the greatest possible distance d from the mirror to the point where the reflected rays meet?
