The focal length of the mirror … Magnification is the increase in the image size produced by spherical mirrors with respect to the object size. For make‐up and shaving mirrors … Mirrors change the direction of light through reflection. How the image appears usually depends on the geometry of the lens or mirror… 2) Magnifying mirrors are rated for their power of magnification based on how much bigger they make an object look. Both mirrors and lenses can create images. What will be the distance of the object, when a concave mirror produces an image of magnification m? Solved Example for You. Magnification by Spherical Mirrors. A plain flat mirror would be rated at 1X and one that makes an object 3 times larger would be rated at 3X. 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 … Q. 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. 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 … Learn more about Reflection of Light here. magnification… focal length: distance from the center of a lens or curved mirror to its focal point. Hence, the expression for magnification (m) becomes: m = h’/h = -v/u. Images may be upside-down, right-side-up, larger or smaller. Lenses bend the direction of light through refraction.
