Stunning Formula Of Power Of Lens
What is the lens formula for convex lens explain its terms.
Formula of power of lens. This assumes that the power of a lens can be calculated using the radii of curvature of two surfaces and the refractive index of the lens material. Power of the lens is -4 D its focal length is. If the focal length is given in meters m the power of the lens if measured in Diopters D as in the unit of power of the lens is diopter.
It is an equation that relates the focal length image distance and object distance for a spherical mirror. Here PPower is expressed in DDioptre and Focal length is expressed in mmeter. The shorter the focal length the greater the power.
The power of a lens is inversely proportional to its focal length. The power of a lens is related to its focal length f by the equation. Power P 1f Where f is thefocal lengthofthelensmirror.
Power of a Lens Formula. Take the reciprocal of 015 to get the power of this prism which is 667. This session will enable students to solve the numerical based on spherical lenses using lens formula magnification and power of lens.
Lens surface power can be found with the. The unit of power of lens is. According to the convex lens equation 1f 1v 1u.
It relates the focal length of a lens with the distance of an object placed in front of it and the image formed of that object. It is given as. 1 The dimensional formula of focal length M 0 L 1 T 0.
