Question

an object is placed in front of a converging mirror at a distance between c and f . state the location and characteristics of an image formed by such a mirror​

Answer 1

Answer:

the object between mirror is equal

Answer 2

Answer:

From mirror formula:

u=

v−f

fv

...............eq1,

when the image formed is erect , then linear magnification will be ,

m=−

u

v

=2(given) ,

or v=−2u ,

by eq1 ,

u=

(−2u)−f

f(−2u)

,

or u=f/2 ,

Now, when image formed is real , then linear magnification will be ,

m

′

=−

u

′

v

′

=−2(given) ,

or v

′

=2u

′

,

by eq1 ,

u

′

=

(2u

′

)−f

f(2u

′

)

,

or u

′

=3f/2 ,

therefore, movement of the object will be =u

′

−u=3f/2−f/2=f ,
