Heartwarming Lens Maker Derivation

The focal length of a lens depends on the refractive index of the lens and the radii of curvature.

Lens maker derivation. Lens Maker Formula With Derivation The formula giving the relation between the focal length f of the lens the refractive index of the material of the lens n and the radii of curvature of its surface R 1 R 2 is known as Lens maker formula. Complete the derivation but the results are compact and sufficiently accurate for most purposes. This formula is only applicable to a lens of a given refractive index placed in air.

In this session Tushar sir will be discussing the topic Lens Maker Equations Mirror Formula with practice multiple choice questions from Class 10 Physic. The Lens Makers Formula is an expression used to find the focal length of a lens for which the refractive index as well as the radii of curvature are known. Its not mandatory but it makes the derivation.

We assume a thin converging lens and that the light rays we are dealing with are close to the principal axis and make very small angles with the principal axis angles of less than 10 o resulting in very small angles of incidence. Ask me anything. It is so called because it is used by lens manufacturers to make lenses of particular power from the glass of given refractive index.

Deriving the Lensmakers Equation Deriving the Lensmakers Equation Level 4 The Lensmakers Equation links the radii of curvature of two sides of a lens the refractive index of the material from which it is made and the focal length of the lens. The Lens Makers Formula Lens manufacturers use the lens makers formula to manufacture lenses of the desired focal length. F focal length of the lens.

It is a relation between the focal length of a lens to the refractive index of its material and the radii of curvature of its two surfaces. Derivation Of Lens Maker Formula Lenses of different focal lengths are used for various optical instruments. Lenses of different focal lengths are used for different optical instruments.
