According to the given statement The total far distance = 88.2cm
A lens equation, sometimes known as a lens formula, is an equation that connects focal length, image distance, as well as object distance. . where v is the distance between the picture and the lens, u is the object distance, and f is the focal length
A lens's power is defined as both the reciprocal of its focal length. It is symbolized by that the letter P. P=1f gives the power P of something like a lens with a focal length of f (in m). The SI unit of lens power is a 'diopter.'
P = -1.16
The expression of the focal length is represented as:
f = 1/p
p is the power.
so,
f = 1/-1.16
= -0.862
= -86.2 cm
the expression for the lens formula is:
1/f = 1/v - 1/u
1/(-86.2) = 1/v - 0
v = -86.2
The total distance is represent as:
d = v + s
so,
d = 86.2 + 2
= 88.2 cm
The total far distance = 88.2cm.
