Question

radius of curvature of a convex mirror is 6m. a object is located at 15m from the mirror.find the position,nature and size of image

Answer 1

Radius of curvature of the convex mirror R = 3 m Focal length of the convex mirror f = R/2 = 1.5 m (positive for convex mirror) Object (bus) distance u = − 5 m Image distance v = ? Mirror formula is: 1/f = 1/v + 1/u 1/1.5 = 1/v + 1/(−5) 1/v = 1/1.5 + 1/5 = (5 + 1.5)/(5 x 1.5) = 6.5/7.5 v = 7.5/6.5 = 1.15 m Position of the image is at 1.15 m behind the mirror.
