Question

a 5 cm tall object is placed perpendicular to the principal axis of a convex lens of focal length 12 CM the distance of the object from the lens is 8 cm using the lens formula the find the position size and nature of the image formed

Answer 1

GOOD EVENING FRIEND

f=12

u=  -8

V=?, Hi=?

Using Len's Formula,

1/f=1/v + 1/u

1/v=1/12 - 1/8

After calculation, V=-12cm

And now using formula of magnification.

Hi/Ho=v/u

Hi/5= -12/-8

After calc, Hi=7.5

The Nature of image is real,inverted, and Enlarged.

Hope this Helpzz
