Answers
Answer:
Given:-
Rear view mirror i.e it is a convex mirror
Radius of curvature ( C ) = 3 m
object distance ( u ) = -5 m
To find:-
image distance ( v )
nature of image
size of image
Formula:-
\implies⟹ \underline{\boxed{\sf \dfrac{1}{f} = \dfrac{1}{v} + \dfrac{1}{u}}}
f
1
=
v
1
+
u
1
\implies⟹ \underline{\boxed{\sf m = \dfrac{-v}{u}}}
m=
u
−v
Solution:-
\implies⟹ \sf\dfrac{1}{3}
3
1
= \sf\dfrac{1}{v}
v
1
+ \sf\dfrac{1}{-5}
−5
1
\implies⟹ \sf\dfrac{1}{v}
v
1
= \sf\dfrac{1}{3}
3
1
+ \sf\dfrac{1}{5}
5
1
\implies⟹ \sf\dfrac{1}{v}
v
1
= \sf\dfrac{3+5}{15}
15
3+5
\implies⟹ \sf\dfrac{1}{v}
v
1
= \sf\dfrac{8}{15}
15
8
\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
