Aconvex lens has a focal length of 16.5 cm. where on the lens axis should an object be placed in order to get a virtual, enlarged image with a magnification of 1.90?

Object should be placed at a distance, u = 7.8 cm

Given:

focal length of convex lens, F = 16.5 cm

magnification, m = 1.90

Solution:

Magnification of lens, m = -

where

u = object distance

v = image distance

Now,

1.90 =

v = - 1.90u

To calculate the object distance, u by lens maker formula given by:

u = 7.8 cm

Object should be placed at a distance of 7.8 cm on the axis of the lens to get virtual and enlarged image.

he . if i may ask what i your question exactly?

explanation:

i am pretty sure it is c because when people are closer together, they cannot move as freely. picture being in a mostly full elevator, for instance. the people are right next to you, and you can barely move.
