Question

(ii) A pin which is 2cm long is placed at a distance of 16 cm from a convex lens. Assuming
it to be perpendicular to the principal axis, find the position, size and the nature of the
image if the focal length of the lens is 12cm.​

Answer 1

Answer:

Here distance of object u=−16cm

Focal length of lens is f=12

So

f

1

=

v

1

−

u

1

So

12

1

=

v

1

−

−16

1

v=48cm

Image is real

Magnification for lens is m=

u

v

=

−16

48

=−4

Inverted image and magnified.

Size of image is h=4×h

i

=4×2=8cm
