Image distance with direction sign

—

Paraxial thin lens inside air; positive image distance real, negative virtual. Aberrations and lens thickness no dey included.

Formula

Use 1/f = 1/dₒ+1/dᵢ and m = −dᵢ/dₒ. f na focal length, dₒ na object distance, and dᵢ na image distance for di same unit. Converging focal length and real object distance dey positive; m na lateral magnification.

Use distances with signs find image distance and magnification.

Example wey show the calculation

Focal length (cm); positive for converging lens
10
Object distance (cm); positive for real object
30
Image distance with direction sign
15 cm
Magnification across the image
-0.5

We check inputs for missing values and allowed ranges. Result wey pass the finite numeric range no go show. Rounding affect wetin display, while calculation use the model numeric precision.

Check your units and assumptions before you rely on result. Changing label no convert currency or physical unit.
