Best Lens Maker Formula For Concave Lens

In this session Tushar sir will be discussing the topic Lens Maker Equations Mirror Formula with practice multiple choice questions from Class 10 Physic.

Lens maker formula for concave lens. Their two surfaces are parts of the surfaces of spheresEach surface can be convex bulging outwards from the lens concave depressed into the lens or planar flat. Lenses of different focal lengths are used for different optical instruments. Considering the refraction of a point object on the surface X P 1 Y the image is formed at I 1 who is at a distance of V 1.

The focal length of a lens depends on the refractive index of the lens and the radii of curvature. Remember that K shape represents the shape of the lens which remains constant. 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.

Equation 2432 gives the focal length of a double convex lens ie a lens for which both surfaces are convex in. Typically the lens axis passes through the physical. Simulation of image formation in concave and convex lenses.

Lens Makers Formula - example Consider a convex lens or concave lens of absolute refractive index μ 2 to be placed in a rarer medium of absolute refractive index μ 1. Lens manufacturers use the lens makers formula to manufacture lenses of the desired focal length. Construction of simple lenses.

1 recommendation Published in Blogs Physical Science. Move the point named Focus to the right side of the lens to change to a concave lens. Lens manufacturers commonly use the lens maker formula for manufacturing lenses of the desired focal length.

The following assumptions are taken for the derivation of lens maker formula. Ray Optics and Optical InstrumentsTo. Lens Makers formula is a formula that relates focal length radii of curvature and refractive index of the lens.
