Question

A convex lens of focal length 10Cm is given. Calculate maximum and
minimum magnification produced by it. ​

Answer 1

The magnification of convex lens is 3.5.

Explanation:

Given that,

Focal length = 10 cm

Least distance of distinct vision = 25 cm

To calculate the magnification, use the formula as

m=(1+\dfrac{D}{f})m=(1+

f

D

)

Where, D = Least distance of distinct vision

f = focal length

Put the value into the formula

m=(1+\dfrac{25}{10})m=(1+

10

25

)

m=3.5m=3.5

Hence, The magnification of convex lens is 3.5.
