magnification of lens and mirror

Images may be upside-down, right-side-up, larger or smaller. 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 … In the science of optics, the magnification of an object like a lens is the ratio of the height of the image you can see to the height of the actual object being magnified. h image = m h object. The magnification of the thin lens system is. I have drawn the element as an interface, though it could equally well be a lens (or, if I were to fold the drawing, a mirror). They have a variety of curved surfaces, depending on their function. The core differences between the mirror and lens would be due to its construction and working. The magnification (m) of lens can also be calculated in terms of image distance (v) and object distance (u), if we do not know the size (height) of object and image. A plain flat mirror would be rated at 1X and one that makes an object 3 times larger would be rated at 3X. The mirror is a device is based on the principle of reflection whereas the lens is based on the principle of refraction. Assuming, as ever, that angles are small, we have \[\text{magnification} = \dfrac{\theta_2q}{\theta_1p}.\] If the magnification is negative, then the image is inverted with respect to the object. Let’s keep it simple—they are lightweight, they are small, and they are affordable. Both these devices are used in various industries such as photography or astronomy etc. For make‐up and shaving mirrors the most common ratings are 3X, 5X, 7X and 10X. How the image appears usually depends on the geometry of the lens or mirror, and also on the location of the object and the observer. Lenses bend the direction of light through refraction. Both mirrors and lenses can create images. An image of height \(h'\) is formed at a distance \(q\) of an object of height \(h\) at a distance \(p\). It will always less than 1. The Pros of Mirror Lenses. Mirrors change the direction of light through reflection. 2) Magnifying mirrors are rated for their power of magnification based on how much bigger they make an object look. m = -v/ u m= h'/h It will be always negative because virtual and erect image is formed by the convex mirror. Mirrors can also be used to form images. For instance, a lens that makes a small object appear very big has a high magnification, while a lens that makes an object appear small has a low magnification. Difference Between Mirror and Lens. Thus, m = … The most expensive telephoto lens currently sold at B&H (the Sony FE 600mm f/4 GM OSS) costs $12,995.The most expensive mirror lens sold at B&H (the Rokinon Reflex 300mm f/6.3 ED UMC CS) costs $299.The 600mm Sony is 17.68" long and weighs 6.7 lb.
