The radius of curvature of a convex mirror used as a rear view mirror in a moving car is 2.0 m. A truck is coming from behind it at a distance of 3.5 m. Calculate
(a) position, and
(b) size, of the image relative to the size of the truck. What will be the nature of the image ?
Radius of curvature , R = 2m
F = R/2 = 2/2 = 1 m
Object distance from mirror = 3.5m
Using the mirror formula,
(a) Image distance is 0.77 m behind the mirror
(b)m = v/u = 4.5 ; The nature of the image is Virtual and erect
