Ray Diagram Lens Equation. The magnification m of an image is the ratio between the image and object height. Principal axis the line passing through the centres of curvature of the lens.
Optics cheat sheet reflection of light reflection is the turning back of the light from the surface it hits. Ray diagrams for lenses. The distance that lies between the image and the optical centre of the lens.
It can be derived from a geometric analysis of ray tracing for thin lenses and is given by 1 do 1 d 1 f 1 d o 1 d i 1 f.
Ray diagram lens equation. Substitutions and algebraic steps are shown. The lens equation an image formed by a convex lens is described by the lens equation 1 u 1 v 1 f where uis the distance of the object from the lens. So lets talk about the lens equation the lens equation allows us to do geometric optics but in.
