LENSES By Jamie Ortiz

Refraction occurs in both concave and convex lenses. A lens is a piece of material in which light is able to pass through and is used to refract light.

There are 2 types of lenses: TWO TYPES OF LENSES There are 2 types of lenses: CONVEX CONCAVE

Concave Lens A concave lens is thinner in the middle than at the edges and causes light rays to spread apart (divergence) It looks like there is a cave on both sides!! So, it must be concave!!

Convex Lens A convex lens or magnifying glass is thicker in the middle then on the ends which causes the light rays focus (converge)

CONCAVE AND CONVEX LENSES Concave lenses make light rays move away from each other or spread out A convex lens can focus the light that enters it and direct it to one point.

Convex Lenses and Images Depending on where you hold the lens--the image you see will either be right side up (real image) or upside down(virtual image)

Concave Lenses and Images A concave lens produce upright images that are smaller than the real object.

Example of CONCAVE lenses Nearsighted eyeglasses (can’t see far away)

Examples of CONVEX lenses Magnifying glass Cameras Telescopes Our Eyes Glasses

LENSES AND VISION NEARSIGHTED- Difficulty in seeing objects far away FARSIGHTED- Difficulty is seeing objects up close Concave Lens Convex Lens

Which is concave and which is convex?
