Answer» answer. BASIC OPTICS We KNOW that image is of same hight than that of the object (in LENSES) only when the OBJ. is placed AT 2F1(C). AND A COMMON FORMULA WE KNOW IS THAT 2F approximately equals RADIUS OF CURVATURE.... THEREFORE, distance btw obj and LENS is — 28 . = 16cm. AND SINCE THE IMAGE IS AS FAR FROM LENS AS OBJ IS:— DISTANCE BTW OBJ AND IMAGE IS 2*16 . = 32 HOPE IT HELPS PLZ RATE BRAINLIST!!

answer.

BASIC OPTICS

We KNOW that image is of same hight than that of the object (in LENSES) only when the OBJ. is placed AT 2F1(C).

AND A COMMON FORMULA WE KNOW IS THAT

2*F approximately equals RADIUS OF CURVATURE....

THEREFORE, distance btw obj and LENS is — 2*8

. = 16cm.

AND SINCE THE IMAGE IS AS FAR FROM LENS AS OBJ IS:—

DISTANCE BTW OBJ AND IMAGE IS 2*16

. = 32

HOPE IT HELPS
