Question

A convex mirror used on a moving automobile as aradus of curvature of 3m .if a truck is following is a constant it at constant distance of 4.5 m find the progress in nature and magnification of the image.​

Answer 1

Explanation:

R=+3m⇒f=2+3m

U=−5m

By Mirror formula:

v1+u1=f1⇒v1+(−5)1=52

⇒v1=32+31

v1=1513

⇒v=1315≃1.1538m behind the mirror

m=hohI=−(uv)⇒hI=(u−v)ho
