WebExplanation: To find the position of the object, we can use the mirror formula for spherical mirrors, which is given by: 1 f = 1 v + 1 u where: f = focal length of the mirror v = distance of the image from the mirror u = distance of the object from the mirror Given; f = 17 c m Webf= focal length of the concave mirror = 3 cm putting the values, Image distance of mirror is -6cm 2. The focal length and the object distance in case of a convex mirror are 6 cm and 8 cm respectively. Calculate the image distance. Ans. From the mirror formula, Using sign convention for convex mirror, u= object distance= 8cm
