Question

define magnification in terms of image distance and object distance .

please answer it quickly ​

Answer 1

Answer:

Magnification is the ratio of height of the image(h') to the height of. the object(h). It is also equal to negative of the ratio of the image distance(v) to object distance(u).

Answer 2

★ Magnification gives a relative extent to which image is magnified with respect to object size.

$\star { \boxed{ \sf{magnification = \frac{ - v}{u} }}}$

where

-v is Image distance

u is Object distance

★ For lens,

${ \boxed{ \sf{magnification = \frac{ v}{u} }}}$
