Question

the maximum magnification that a convex lens of a focal length 2.5 cm is​

Answer 1

m= 1 + d/f


Now take d as least distant of vision that is 25 cm

So m= 1 + 25/2.5

= 1 + 10

= 11

Answer 2

Answer:

Formula to calculate maximum magnification of an object through a convex lens is:

• M = 1 + d / f

Here, d refers to the distance of least vision and f refers to focal length.

Since there is no 'd' specified in the question, we take d to be least distance of vision is 25 cm.

Since we take distance in cm, we take focal length also in cm.

Hence, Substituting in the formula we get,

⇒ M = 1 + 25 / 2.5

⇒ M = 1 + 10

⇒ M = 11

Hence the maximum magnification that can be produced by convex lens of focal length 2.5 cm is 11.

Hope it helped !!
