Webb18 nov. 2024 · Solution: The radius of curvature of the mirror = 30 cm Thus, the focal length of the mirror = = 15 cm Example 4: An object is placed at a distance of 15 cm from a concave mirror of focal length 10 cm. Find the position of the image. Solution: We have u = –15 cm and f = –10 cm Using the relation, we get or or v = –30 cm Webb7 apr. 2024 · Mirror Formula The distance of an object on principal axis from pole of spherical mirror is called object distance (u). The distance of position of image on principal axis from pole of spherical mirror is called image distance (v). Loaded 0% 1/u + 1/v = 1/f Magnification (m) It is defined as ratio of size of image (h’) to size of object (h).
