Question

You are provided with two lenses of focal length 20 cm and 30 cm, respectively. Which lens will you use to obtain more convergent light?

Answer 1

❗❗ answer ❗❗

lense with focal length 20cm because uts power is more by the relation

$f = \frac{1}{p}$

hope!!...it helps uhh...❣️

The power ( P ) and focal length ( f ) of a lens are related by the following equation :

$\: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \large{\boxed{\bf{\green{P = \frac{1}{f} }}}}$

Power of a lens is inversely proportional to the focal length, therefore lens having focal length of 20 cm will provide more convergence.
