how magnification by convex lens depends on its focal length .

Answers

Answered by harshlf4p50p4g

simply by the formula of magnification which is
M=
$\frac{1}{f}$
since focal length is inversely proportional to to magnification so it magnification of convex lens depends on its focal length...

PLEASE UPVOTE AND PUT ME ON BRAINLIST!!!

sapana4: I know it ,but how?

harshlf4p50p4g: ummm..ok..m texting you for the explanation

harshlf4p50p4g: ok leave it...see

harshlf4p50p4g: inversly proportional means if focal length would be increased then becz of inversly proportinality the magnification would decrease nd vice versa....so it depends upon the the focal length

harshlf4p50p4g: brainlist me!! and agar abhi bhi nai samjh aaya then say...i will text you then!

Answered by ram337

m = -v/(-u) =f/u-f by lens formula

harshlf4p50p4g: wrong

harshlf4p50p4g: check my answer...

sapana4: perhaps ,if focal length of convex lens increase then magnification will decrease and when focal length decrease then magnification will be increase.
