A convex mirror used for rear view on an automobile has a radius of curvature of 3.00 m. If a bus is located at 5.00 m from this mirror, find the position, nature and size of the image.

Explanation

Convex mirror, R=2 m `rArr f=2//2 =+1m, u=-5 m , v= ?`
`1/v+1/u=1/f rArr 1/v=1/f-1/u rArr 1/v=1/1-1/(-5)`
`rArr 1/v=(5+1)/5=6/5 :. v=5/6=0.8 m `
`rArr m =(-v)/u=(-0.8)/(-5.0) =0.16` (Image is erect, virtual and diminished)
