(a) Number Units No unitscm The image behind a convex mirror (radius of curvature = 58.0 cm) is located 25.0 cm from the mirror. (a) Where is the object located (give the distance to the mirror) and (b) what is the magnification of the mirror?

Explanation / Answer

R = 58 cm f = R/2 = 29 cm v = 25 cm a). (1/u) + (1/v) = 1/f => (1/u) + (1/25) = 1/29 => u = -181.25 cm image is 181.25 cm infront of the mirror. b). m = -v/u => m = -25/(-181.25) = 0.138
