A ray of light parallel to the optic axis of a concave mirror is reflected back through the focal point.
Explanation:
- An optical axis is a line alongside which there's some degree of rotational symmetry in an optical system together with a camera lens, microscope or telescopic sight.
- A concave mirror, or converging mirror, has a reflecting surface this is recessed inward . Concave mirrors mirror light inward to one focal point. They are used to focus light.
- Rays of light parallel to the principal axis of a concave mirror will seem to converge on a point in the front of the mirror somewhere between the mirror's pole and its center of curvature. That makes this a converging mirror and the factor wherein the rays converge is referred to as the focal point or focus .
