Question

the radius of curvature of a convex mirror used as real view mirror in a moving car is 2m. a truck is coming from behind it at a distance of 3.5m calculate a) position and b) size of the image relative to the size or the truck what will be the nature of the image?​

Answer 1

Answer:

Given,

Radius of curvature, R=2m

object distance, μ=3.5m

focal length, f=

=0.22

Image will be formed at 0.78m & will be virtual crect and diminished.

Image will be 0.22 times the truck.
