Notice the incoming light rays from the object are parallel, indicating the object is very far away. Concave mirrors have the focal point (f) in front of the mirror, and convex mirrors have the focal point behind the mirror. Spherical vs. New Resources. ) In every case, convex or concave, if the rays leaving the lens actually intersect, the image is real. Case 2 iii. For each case, draw the 3 principal rays to locate the image. b) real, inverted, and smaller. ray diagram of concave lens image formation by concave lens concave mirror ray diagram convex mirror ray diagram image formation by convex lens experiment converging and diverging lenses ray. click near tip of the object, and drag it to where you like it and release the mouse button. In today's class, Abhishek Sir will explain the topic and. 23-3 Spherical Mirrors: Ray Diagrams. An incident ray which is parallel to the optic axis is refracted as if it came from the image focus of the lens. The angle of incidence is always equal to angle of reflection.

The ray parallel to the principal axis and the ray that hits the center of the mirror are drawn. Light from different points on the pencil, immersed in water refracts and appears to come from a point above the original position. The ray parallel to the principal axis and the ray that hits the center of the mirror are drawn. It will give a virtual upright image if the object is within the focal length. An object near a convex lens produces a 1. This first step is the same regardless of the type of lens. See Figure 6. Figure 3-2c shows plane wave fronts of light bent by a lens into circular (spherical in three dimensions) wave fronts that then converge onto a focal point F. Any ray that aims the first nodal point emerges from the second nodal point undeviated but slightly displaced.

CONCAVE MIRRORS Extra Practice Worksheet a) Draw a ray diagram for each to locate the image. In preparation for our exam, I handed out this practice sheet. Drawing a ray diagram for concave mirrors is similar to drawing them for convex mirrors. The light rays are bent by refraction as they pass through the lens and form a focused image to the right of the lens. Concave and convex lenses are the two most common types of lenses, and they cause light rays to diverge and converge, respectively. Author: Lenore Horner.
