Question

a radices of rear view Convee mirros with Cusvatuse of 6m is resed as mirror for a vehicle. If 10 m from this mirros, find the position nature and size of the image а a bus is located at​

Answer 1

Here the bus is the object of the convex mirror whose image is formed. The position of the bus (or object) from the mirror is given to be u=5⋅00m. The radius of curvature of the convex mirror is given to be R=3⋅00m, then its focal length will be f=R2=32=1⋅5m.

HOPE SO IT HELPS YOU

Answer 2

Explanation:

given :

R=3m

f=R/2=3/2=1.5m

u=5m

v=?

Mirror formula:

1/f=1/u+1/v

by sign conventions:

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

1/v=1/1.5+1/5-6.5/7.5

v=7.5/6.5

= 1.15m

The image is virtual seen at the back

of mirror.

m=hi/ho=-v/u

-1.15/-5-0.23

Image is erect and diminished in size by a factor of 0.23
