Question

The distance between real object and its image in a convection mirror of focal length 12cm is 32cm .Find size of image if object is of 1cm in size....Also depict nature of image former....With diagram plzzz

Answer 1

1/v+1/u=1/f

Let u=x 

V=32-x

Substituting these values in the mirror formula ,we get

X^2 -8x - 384 

We get x=16

And from that we can say v=16

Therefore h1/h2=16/16=1
