Question

the radius of curvature of a convex mirror used as a rear view mirror in a moving car is '20' m a truck is coming from behind it at a distance of 3.5 metre calculate the a)position b)size of the image relative to the size of truck what will be the nature of the image.​

Answer 1

Answer:

object distance(u)=-20m

radius of curvature(R)=3.5m

focal length (f)=3.5/2

=1.75

we have

1/v+1/u=1/f

1/v=1/f-1/v

1/v=1/1.75-1/20

1/v=4-35/700

v=-0.04

Answer 2

here's your answer hope it helps
