Using lens formula the equation for magnification can also be obtained as . It is denoted by the letter ‘m’ and is given by, m = h 2 /h 1 = v//u = (f-v)/f = f/(f+u) This equation is valid for both convex and concave lenses and for real and virtual images. a) Magnification = $\frac{length of drawing}{length of object}$ b) Staining is … What is the formula for calculating linear magnification of a specimen when using a hand lens . Answer: Q1. Linear magnification is the ratio of the size of object and image. and the thin-lens equation. The required linear magnification is the ratio of the desired image diameter to the diamond’s actual diameter (). The linear magnification or magnification of a spherical mirror may be defined as the ratio of the size (height) of the image to the size (height) of the object. a. The linear magnification produced by a spherical lens (convex or concave) is defined as the ratio of the height of the image (h′) to the height of the object (h). Understanding the focal length of lenses was crucial to combining their powers. Because the jeweler holds the magnifying lens close to his eye, we can use Equation \ref{eq13} to find the focal length of the magnifying lens. Angular magnification is the ratio of the angle subtended by object and image. The linear or transverse magnification is defined as the ratio of the size of the image to that of the object. Zacharias Jansen and his father combined lenses from simple magnifying glasses to build microscopes and, from there, microscopes and telescopes changed the world. But how can I prove the equation mathematically? Subtended angles are related to the linear size by non-linear trigonometric functions and depend on the distance from image to eye. As the object is always placed above the principal axis so the magnitude of h 1 is always positive. If the camera forms an image which is 6mm high, (a) What is the magnification; (b) How far must the camera film be behind the lens for the image to be formed. Waves And Optics - Lenses Lens Formula: Magnification Linear Magnification (m) = height of image height of object OR = Image distance Object distance Example: A building is 6m high, and it is 80m from a converging camera lens. It is a pure ratio and has no units. Solution. The required linear magnification is the ratio of the desired image diameter to the diamond’s actual diameter (Equation \ref{eq15}). a) What is the formula for calculating linear magnification of a specimen when using a hand lens b) Give a reason why staining is necessary when preparing specimens for observation under the microscope. Keep in mind that subsequent lenses can continue to invert your image. Answers . The magnification of a mirror is represented by the letter m. Thus m = Or m = where, h 2 = size of image h 1 = size of object. For each lens, treat the image of the previous lens as its object and use the lens equation and magnification equation to find your answers. Before the 1590s, simple lenses dating back as far as the Romans and Vikings allowed limited magnification and simple eyeglasses.
