KEY CONNECTIONS

Formulas

Γ = \frac{H}{h}

Γ = H / h

Γ = \frac{f}{d}

Γ = f / d

NOTATION

$\Gamma$: Lens magnification is the ratio of image size to object size.
$H$: Image height is the linear size of the image of an object.
$h$: The height of an object is the linear size of the object in question.
$f$: Image distance is the distance from the lens to the resulting image.
$d$: Object distance - the distance from the lens to the object in question.
