how far from a converging lens with a focal length of 35 cm should an object be placed to produce a real image which is the same size as the object?



Answer :

A converging lens with a focal length of 35 cm should an object be placed to produce a real image .The distance from the converging lens is 70 cm.

What is Converging lens ?

A lens that converges light rays that are moving parallel to its main axis is known as a converging lens. The shape of convergent lenses can be used to identify them; they are somewhat thick in the middle and narrow at the upper and lower margins.

Parameters:-

16 cm is the converging lens's focal length, or f.

Magnification equals m - q / p.

where

q is the image's separation from the lens.

m = - q/p - 1 = - q/p

q = p

Lens equation : 1/p + 1/q = 1/f then

q = p into equation

1/p + 1/p = 1/35

p = 70cm
