Convex and Concave Lenses Solving the Lens Mystery 0 Lynn Garner & Sharon Holloway

Lenses and Light Lenses are curved pieces of glass that can be convex or concave. Concave lenses cause light rays to spread out (diverge). Convex lenses cause light to come together (converge) to a focal point.

Refracted Light –Convex & Concave

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

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.
