A Convex Lens is a type of spherical lens that converges the ray of light coming from the object. Let's practice problems involving both the lens and magnification formulas in convex and concave lenses. 8 IMAGE FORMATION BY CONVEX LENS. supplemented by the use of eyeglasses or even require lens replacement to maintain perfect vision. There are three types of convex lenses - PLANO- CONVEX LENS CONCAVO CONVEX LENS DOUBLE-CONVEX LENS . Convex lens: A convex lens is also called a positive lens or a converging lens. If you're seeing this message, it means we're having trouble loading external resources on our website. Difference Between Concave and Convex Lens Concave and Convex are two types of lenses that possess variation in physical shape as well as their properties. The crucial difference between concave and convex lens is that a concave lens diverges the light rays that incident on its surface. 1.

Pick a point on the top of the object and draw three incident rays traveling towards the lens. Out purpose here is to look at some of the more important properties of lenses. The method of drawing ray diagrams for double convex lens is described below. It is thick at the centre and thin at the edges. 9 SL. WHAT IS CONVEX LENS ? The description is applied to the task of drawing a ray diagram for an object located beyond the 2F point of a double convex lens. A lens is essentially a transparent structure having two convex surfaces which bend incoming light rays following the familiar Snell’s Law n sin( )=const .
