Unbelievable Lens Maker Diagram

Advanced Physics questions and answers.

Lens maker diagram. The lensmakers formula relates the radii of curvature the index of refraction of the lens the thickness of the lens and the focal length. See for a diagram of a positive converging lens. In this case the lens is called a positive or converging lens.

You can change the focal length using a slider. Where is the focal length of the lens is the distance of the object from the lens and is the distance the image is formed from the lens. By manipulating the object and lens locations you can create real or virtual images.

Move the tip of the Object arrow to move the object. This Demonstration lets you visualize the ray diagrams for converging and diverging lenses. The diagram was started by drawing the two circles of equal size then overlapping them to make the lens.

A ray proceeding parallel to the principal axis will diverge as if he came from the. The object used is a hole and cross-wire in a white screen illuminated by a pearl electric lamp. Shows how to draw ray diagrams to locate the image formed by a convex lens.

The rays parallel to the principal axis and the ray through the center of the lens are drawnLocators allow you to drag both the object and the lens. The lens is set up in a suitable holder with a plane mirror behind it so that light passing through the lens is reflected back again. Simulation of image formation in concave and convex lenses.

The radii of curvature here are measured according to the Cartesian sign conventionFor a double convex lens the radius R 1 is positive since it is measured from the front surface and extends right to the center of curvature. Image formation by convex lens ray diagrams. Concave Lens End Width of Lens a 75 mm Middle Width of Lens b 12 mm Length of Lens 2 562 mm O Paste a copy of your ray tracing diagram of the concave lens given in Capstone.
