Question

A convex mirror with R=3cm is used as a rear view mirror in an automobiles If a bus is located at 5cm from this mirror. Find the position and size of the image​

Answer 1

Answer:

1/f = 1/v + 1/u

1/1.5 + 1/v +1/-5

10/15 + 1/5 = 1/v

10/15 + 3/15 = 1/v

1/v = 13/15

= v = 13/15= 1.15 m

thus distance of the image 'v' is 1.15m behind the mirror

Explanation:

now by magnification formula , we get

m = -v/u

m =(-1.15)/-5 = 155/500

= 0.223

Thus , the image is virtual erect and smaller in size
