Question

A convex mirror used on a bus has a focal length of 200 cm. If a scooter is located at 100 cm from the mirror find the position, nature and magnification of the image formed in the mirror

Answer 1

f=200 cm
u=100 cm
Mirror formula=1/v+1/u=1/f
1/v=1/f-1/u
=1/200-1/100
=1/200
v=200cm
Position of image is 200 cm away from mirror and behind the mirror.
Magnification, m=-v/u
m=-200/-200
m=1
Hope it will help you
