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
