IIT JEE , AIEEE Forum - Physics , Optics - What happens when a convex lens is cut into 2 parts???

rishulmatta16

how wil the position or nature of image vary if a lens is cut into two parts nd is placed at different positions on principal axis???

anchitsaini

well the nature of image does not vary.
the only thing that has to be done is to consider the cut part as a normat convex lens and then solve.

spideyunlimited

if u use half of the lens, the intensity or brightness of image will become half... and other properties will remain same such as virtual or real, erect or inverted, magnified or diminished

When u cut it into two halves

(a) along it's principal axis

then

focal length will not change,intensity changes

(b) along an axis passing through it perpendicular to principal axis

focal length changes to twice each

hii

well yeah.. when we cut accross the principal axis .. nothing happens .. as ppl hav pointed out just the intensity changes ..

it is one of the celebrated problems .. appear frequently in different forms ..

cheers
