You can also find Mirror Formula and Magnification - Light Reflection and Refraction, Class 10, Science | EduRev Notes ppt and other Class 10 slides as well. The mirror formula is applicable for both, plane mirrors and spherical mirrors (convex and concave mirrors). The Mirror formula explains how object distance (u) and image distance (v) are related to the focal length of a spherical mirror. out Class 10 lecture & lessons summary in the same course for Class 10 Syllabus. Object distance is the distance of the object from the pole of the mirror; denoted by the letter u. The document Mirror Formula and Magnification - Light Reflection and Refraction, Class 10, Science | EduRev Notes is a part of the. of Mirror Formula and Magnification - Light Reflection and Refraction, Class 10, Science | EduRev Notes for Class 10, the answers and examples explain the meaning of chapter in the best manner. Concave mirrors are also known as converging mirrors since the rays converge after falling on the concave mirror while, the convex mirrors are known as diverging mirrors as the rays diverge after falling on the convex mirror. depends only on the radius of mirror and is independent of wavelength of light and refractive index of medium so the focal length of a spherical mirror in air or water and for red or blue light is same. Required fields are marked *.

It is also given in terms of image distance and object distance. It is used as rear-view mirror in vehicles. A mirror formula can be defined as the formula which gives the relationship between the distance of object ‘u’, the distance of image ‘v’, and the focal length of the mirror ‘f’. The mirror equation expresses the quantitative relationship between the object distance (do), the image distance (di), and the focal length (f). (iii) Do not put the sign of unknown variables. it is erect and formed above the principal axis. using search above. perfect preparation. The principal axis is taken as the x-axis of our coordinate system. Mirror formula is applicable for all spherical mirrors for every position of the object. c. The object is always placed on the left side of the mirror which implies that light falling from the object on the mirror is on the left-hand side. Class 10 Mirror Formula and Magnification - Light Reflection and Refraction, Class 10, Science | EduRev Notes Summary and Exercise are very important for It is equal to the ratio of image distance to that of object distance. Linear magnification when the image is real: As we normally take the object above the principal axis, therefore, h, is always negative. As the object is always above the principal axis, the height of the object is always positive. Linear magnification when the image is virtual : 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. Your email address will not be published. The relation between the distance of the object from the pole of the spherical mirror (u), the distance of the image from the pole of the spherical mirror (v) and its focal length (f) is given by the mathematical formula : It must be remembered that focal length (f) of a spherical mirror is half the radius of curvature (R). Important points in using the mirror formula : (i) Put the correct signs of known variables according to the sign convention. 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 Mirror formula explains how object distance (u) and image distance (v) are related to the focal length of a spherical mirror. Spherical mirrors in which inward surfaces are painted are known as convex mirrors while the mirrors in which outward surfaces are painted are known as concave mirrors. If you want Mirror Formula and Magnification - Light Reflection and Refraction, Class 10, Science | EduRev Notes Let’s learn about formula and magnification produced by spherical 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. Stay tuned with BYJU’S to learn more about spherical mirrors, surface tension and much more. Thus, h0 and hi are both positive. The positive magnitude of magnification indicates virtual and erect image. Magnification by Spherical Mirrors. 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. d. All the distances parallel to the principal axis are measured from the pole (p) of the mirror. (iii) If the calculated sign turns out to be positive, then the variable calculated is behind the mirror. EduRev is a knowledge-sharing community that depends on everyone being able to pitch in when they know something. this is your one stop solution. The real image is always inverted and is formed below the principal axis.Therefore, hi is always negative. Complete
