Question

the magnifying power of convex lens of focal length 5 cm is??​

Answer 1

very simple ,magnifying power of the simple microscope is given by

m=1+D/f

here D is 25 cm (the least distance of clear vision) ok than use it.

Answer 2

The magnifying power of the convex lens is 6.

Explanation:

It is given that,

Focal length of the convex lens, f = 5 cm

To find,

The magnifying power of the lens.

Solution,

The formula of the magnifying power of a lens is given by :

$m=1+\dfrac{D}{f}$

D is the least distance of distinct vision, D = 25 cm

$m=1+\dfrac{25}{5}$

m = 6

The magnifying power of the convex lens is 6. Hence, this is the required solution.
