Hence, the expression for magnification (m) becomes: m = h’/h = -v/u. Magnification is the increase in the image size produced by spherical mirrors with respect to the object size. Lenses bend the direction of light through refraction. How the image appears usually depends on the geometry of the lens or mirror… Magnification by Spherical Mirrors. Solved Example for You. focal point: for a converging lens or mirror, the point at which converging light rays cross; for a diverging lens or mirror, the point from which diverging light rays appear to originate. The focal length of the mirror … 2) Magnifying mirrors are rated for their power of magnification based on how much bigger they make an object look. What will be the distance of the object, when a concave mirror produces an image of magnification m? Learn more about Reflection of Light here. It is the ratio of the height of the image to the height of the object and is denoted as m. The magnification, m produced by a spherical mirror … A plain flat mirror would be rated at 1X and one that makes an object 3 times larger would be rated at 3X. For make‐up and shaving mirrors … Lets apply image magnification equation to second lens m 2 = - 1.15 Second lens has magnification of – 1.15 Image magnification in terms of object/image height is Image generated from first lens going to be object for the second lens h i1 = h o2 From this equation we see that total magnification … focal length: distance from the center of a lens or curved mirror to its focal point. magnification… Both mirrors and lenses can create images. Mirrors change the direction of light through reflection. Images may be upside-down, right-side-up, larger or smaller. Q.
