Lenses

• Lenses bend light in different ways (Refraction and Reflection)

• 2 basic types: Convex and Concave

• Are either simple or complex

Convex Lenses• Make objects appear larger

• Outward shape

• Refracts light

• Focuses light to form an image

Concave Lenses

• Make objects appear smaller

• Diverge (spread out) light

• Inward shape

• Refracts light
