Explanation:

Given:-Rear view mirror i.e it is a convex mirrorRadius of curvature ( C ) = 3 mobject distance ( u ) = -5 m

To find:-image distance ( v )nature of imagesize of image

Formula:-

\implies⟹ \underline{\boxed{\sf \dfrac{1}{f} = \dfrac{1}{v} + \dfrac{1}{u}}}f1=v1+u1

\implies⟹ \underline{\boxed{\sf m = \dfrac{-v}{u}}}m=u−v

Solution:-

\implies⟹ \sf\dfrac{1}{3}31 = \sf\dfrac{1}{v}v1 + \sf\dfrac{1}{-5}−51

\implies⟹ \sf\dfrac{1}{v}v1 = \sf\dfrac{1}{3}31 + \sf\dfrac{1}{5}51

\implies⟹ \sf\dfrac{1}{v}v1 = \sf\dfrac{3+5}{15}153+5

\implies⟹ \sf\dfrac{1}{v}v1 = \sf\dfrac{8}{15}158

\implies⟹ \sf vv = \sf 1.251.25

Nature:- The positive sign of this image shows that it is Virtual and erect image.

Size of this image

\implies⟹ m = \sf\dfrac{-1.25}{-5}−5−1.25

\implies⟹ m = 0.25

hence, this image is smaller than the object
