Q30 of 31 Page 67

A convex mirror with a radius of curvature of 3m is tried as rear view in an automobile. If a bus is located at 5m from this mirror, find the position, nature and size of the image. (AS7)

Radius of curvature (R) = 3 m

Focal length (f) = R/2 = 3/2 m Image distance(v)= ?


Object image (u) = - 5 m


Using mirror formula :






v = 15/13 m = 1.15 m


Thus, the image will be formed behind the mirror at a distance of 1.15 m from the mirror. The image is virtual, erect & diminished.
