Question

what is linear magnification?​

Answer 1

Answer:

Linear magnification

Explanation:

Linear (sometimes called lateral or transverse) magnification refers to the ratio of image length to object length measured in planes that are perpendicular to the optical axis. A negative value of linear magnification denotes an inverted image.

Answer 2

heya !

linear magnification is a ratio between the size of an image to the size of the object.

it's formula is :-

$\huge \fbox \blue{m=hi/ho}$

where,

• hi = height/size of image
• ho = height/size of object
• m = magnification.

Liner magnification can also be found by the ratio btw the image distance with that of the object distance.

NOTE:- that image distance is taken as -ve in case of mirrors but +ve in case if lens.

it's given by the formula :-

for mirror:-

$\huge \fbox \blue{m=-v/u}$

for lenses :-

$\huge \fbox \blue{m=v/u}$

where,

• m = magnification
• v = image distance
• u = object distance
