Question

in above experiment if u= 30 cm and v= 65cm then linear magnification m=?​

Answer 1

Answer:

linear magnification is defined as the ratio of height of image to the height of object

m=- h2/h1 = -v/u

= -65/30=-2.16

Answer 2

So, Linear magnification is $-2.166$

Explanation:

$u=30cm$ and $v=65cm$ then linear magnification$(m)=?$

Linear magnification:-

                                      If the image and object are in the same medium it is just the image distance divided by the object distance. negative sign is used on the linear magnification equation as a reminder that all real images are inverted.

Therefore, $m=-\frac{height \,of\, image}{height\, of object}$

∴$m=-\frac{v}{u}$

⇒$m=-\frac{65}{30}$

∴$m=2.166$

∴ Linear magnification is $-2.166$
