It is also given in terms of image distance and object distance. Thus, Linear magnification for real images =, In case of virtual image. Magnification of a mirror, m = -v/u Where u= object distance, v = image distance and f = focal length Let's consider an example: A concave mirror has focal length 10 cm and object is placed at distance 15 cm from pole of mirror. out Class 10 lecture & lessons summary in the same course for Class 10 Syllabus. The expression which gives the relation between these three quantities is called the mirror formula which is given as: Mirror formula is applicable for all spherical mirrors for every position of the object. 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 can be expressed as: Here, h is the height of image and h’ is the height of the object. The linear magnification produced by a spherical mirror is equal to the ratio of the distance of the image from the pole of the mirror (v) to the distance of the object from the pole of the mirror (u) with a minus sign. To obtain this type of numerical information, it is necessary to use the Mirror Equation and the Magnification Equation. d. All the distances parallel to the principal axis are measured from the pole (p) of the mirror. A real image can be taken on a screen, but a virtual image cannot be taken on a screen. perfect preparation. The mirror formula is applicable both in spherical mirrors (concave mirrors and convex mirrors) and in plane mirrors. this is your one stop solution. Magnification is also equal to the ratio of image distance to the object distance. The sign convention for spherical mirrors follows a set of rules known as the “New Cartesian Sign Convention”, as mentioned below: a. Linear magnification produced by spherical mirrors : The ratio between the height of the image produced by the spherical mirror to the height of the object is called the linear magnification. In convex mirror, the field of view is increased as compared to plane mirror. Calculating magnification with the help of lens formula: Magnification of a lens is defined as the ratio of the height of an image to the height of an object. Due to their converging property concave mirrors are also used as reflectors in automobiles head lights and search lights. your solution of Mirror Formula and Magnification - Light Reflection and Refraction, Class 10, Science | EduRev Notes search giving you solved answers for the same. Mirror images with their attributes: R, C, f, P, and Principal axis. Thus, h0 and hi are both positive. Your email address will not be published. If you want Mirror Formula and Magnification - Light Reflection and Refraction, Class 10, Science | EduRev Notes just for education and the Mirror Formula and Magnification - Light Reflection and Refraction, Class 10, Science | EduRev Notes images and diagram are even better than Byjus! Magnification is the increase in the image size produced by spherical mirrors with respect to the object size. Concave mirrors give enlarged, erect and virtual image, so these are used by dentists for examining teeth. Spherical Mirrors Mirror Formula: Mirror formula explains how object distance (u) and image distance (v) are related to the focal length of a spherical mirror. Stay tuned with BYJU’S to learn more about spherical mirrors, surface tension and much more. Object distance is the distance of the object from the pole of the mirror; denoted by the letter u. You can download Free Mirror Formula and Magnification - Light Reflection and Refraction, Class 10, Science | EduRev Notes pdf from EduRev by Curved Mirrors. Linear magnification produced by spherical mirrors : The ratio between the height of the image produced by the spherical mirror to the height of the object is called the linear magnification. Object distance is the distance of the object from the pole of the mirror; denoted by the letter u. Let’s learn about formula and magnification produced by spherical mirrors. \( … Class 10. Your email address will not be published. We can define two general types of spherical mirrors. The Mirror formula explains how object distance (u) and image distance (v) are related to the focal length of a spherical mirror. It is used as rear-view mirror in vehicles.
