In convex
mirrors the parallel rays are reflected in such a way that nearly all
of them appear to come from the focal point F, as shown in the
following visual. This is why a distant light source reflected in a
convex spherical mirror appears as a point of light. You can modify the
radius of the mirror's curvature and its width, by clicking on and
dragging the red dots. |
