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). 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. Light reflection, refraction all formulas - mirror, lens, magnification , refractive index, Snell's law - Chapter 9, CBSE Class 10. Have you ever used a magnifying glass to read a page with small print? The magnifying glass makes the words appear much bigger than they actually are. The size of the words increases when we move the magnifying glass towards the page. Lens Maker's Formula Both the mirror equation and the magnification equation also apply to lenses. However, when dealing with lenses the mirror equation is called the Lens Maker's equation.
