Magnification formula: The image is formed with magnification

The image is formed with magnification , the length changes to ma, and the breadth changes to mb, where m is lateral magnification . Areal magnification is defined as the ratio of the area of the image (Ai) and the area of the object (Ao). Light reflection, refraction all formulas - mirror, lens, magnification , refractive index, Snell's law - Chapter 9, CBSE Class 10. Magnification Definition Magnification is the process of a lens refracting an image onto a surface and is defined as the ratio of the distance from the image to the distance from the object. Magnification Example How to calculate magnification ? First, determine the distance of the object from the lens. The Lens formula describes the relationship between the distance of an image (v), the distance of an object (u), and the focal length of lens formula (f) of the lens in optics.
