Thin Lens Equation

The thin lens formula relates the distances from the object to the lens and from the lens to the image to the focal length for a lens of negligible thickness in air.

The sum of the reciprocals of the distance between the image and lens and the distance between the object and lens equals the reciprocal of the focal length.

Formula

QuantityVariable["i", "Distance"]^(-1) + QuantityVariable["o", "Distance"]^(-1) == QuantityVariable["f", "Length"]^(-1)

symbol description physical quantity
i distance between image and lens "Distance"
o distance between object and lens "Distance"
f focal length "Length"
