The formula governing reflection of light from a spherical mirror is (1)/(v) + (1)/(u) = (2)/(R ) , where u = distance of object from pole of mirror, upsilon = distance of image from pole of mirror f = focal length of mirror, R = radius of curvature of mirror. This is known as mirror formula and is applicable equally to concave mirror and convex mirror. m = (I)/(O) = (upsilon)/(u) Read the above passage and answer the following questions : (i) An object is held at a distance of 30 cm in front of a concave mirror of radius of curvature 40 cm . Calculate distance of the image from the object ? What is linear magnification of the mirror ? (ii) The object is moved to a distance of 40 cm in front of the mirror. How is focal length of mirror affected ? (iii) What values of life do you learn from the mirror formula ?

Write the formula for a lens connnecting image distance (v), object distance (u) and the focal length (f). How does the lens formula differ from the mirror formula?
