Convex lenses bulge outwards in the center Bends light inward at a spot just beyond the lens known as the focal point. Concave lenses Thinner in the middle and thicker on the edges Curves light rays outward (diverge). How You See Your Eye Convex Lens - PowerPoint PPT Presentation.

Each of a lens' two faces is part of asphere and can be convex or concave If a lens is thicker at the center than theedges, it is a convex. Convex and Concave Lenses A convex lens often is called a converging lens because when surrounded by material with a lower index of refraction, it refracts . 9 Questions to answer: What's the difference between a LENS and a MIRROR? What's the difference between a CONVEX and CONCAVE lens? 3. Explain WHY . that the lens is drawn as a straight line with arrowheads to represent its shape. All rays should have arrowheads. on them, showing direction of travel. Describe the functions of convex and concave lenses, a prism, and a flat mirror. Draw the ray diagram for a lens and a mirror showing the object and image. CONVEX AND CONCAVE LENSES. OBJECTIVE: To find the focal point and focal length of convex and concave lens. CONVEX LENS – CONVERGING LENS . Lenses. Physics Mrs. Coyle. What phenomenon is evident in lenses? Basic Types of Lenses. Convex. Concave. Convex Lens. Concave Mirrors. Curves inward "Have you ever approached a giant concave mirror? See your Far Sightedness – Convex lense shortens the focal length. Convex lens (converging lens). Concave lens (diverging lens). Parallel rays of light are refracted and meet at the focal point. For a diverging lens, the focal point .
