2 Lenses Convex Lenses Concave Lenses Eyeglasses Flashlight Camera References

3 Lenses Lenses bend light in different ways (Refraction and Reflection) 2 basic types: Convex and Concave Are either simple or complex For more information on lenses, click here Back

4 Convex Lenses Make objects appear larger Outward shape Refracts light Focuses light to form an image Back

5 Concave Lenses Make objects appear smaller Diverge (spread out) light Inward shape Refracts light Back

6 Eyeglasses Simple lens Convex lens corrects far-sightedness Concave lens corrects near-sightedness Back

7 Flashlight Simple lens Convex lens Spreads out light Back

8 Camera Complex lens Contains 6 simple lens elements Can contain both convex and concave lenses Back

Lenses Lenses are curved surfaces that refract light as it passes through. [http://www.ast.cam.ac.uk/~optics/dazle/photos/finished_lenses/lenses_1_to_4_1.jpg]

Convex and Concave Lenses.  A concave lens is thicker at the edges than it is at the center.  It spreads light waves apart.
