Lenses Convex Lenses Concave Lenses Eyeglasses Flashlight Camera References

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

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

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

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

Flashlight Simple lens Convex lens Spreads out light Back

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