WebA lens is a piece of transparent material which concentrates or disperses light rays when passes through them by refraction. According to the shape and purpose of the lens, they … WebFind the intersection of these two rays on the right side of the lens, and draw the image of the object (as shown in the video). Now, draw rays from the edge of the image back to the edges of iris and continue them until they reach the lens, then show them refracting and trace them back to the edge of the object.

http://www.passmyexams.co.uk/GCSE/physics/concave-lenses-convex-lenses.html WebIf you have myopia or nearsightedness, you would use diverging lenses (concave) to shift the focus of your eye lens backwards so that it can focus on the retina. Just the opposite goes for hypermetropia or farsightedness, in which you would use converging (convex) lens to bring the focus closer. In astigmatism, you would use cylindrical lenses.

WebNov 30, 2016 · It determines the amount of light that passes through the lens. To help understand the refraction of light through a convex lens, imagine a convex lens as an arrangement of a number of portions of triangular prisms with a very small glass slab at the center. The base of each prism points towards the principle axis of the lens.
