  4. Concave Mirrors • Make-up mirrors are concave and magnify • Concave mirrors are used in reflectors, spotlights, and headlights focus light into beams

  5. Convex Mirrors • Convex mirrors curve outwards and are wide angle mirrors. • Convex mirrors are like rear view mirrors • They provide drivers and clerks with a wide field of vision.
