Which shows the correct lens equation? The inverse of f equals the inverse of d Subscript o Baseline times the inverse of d Subscript I Baseline. The inverse of f equals StartFraction d Subscript o over d Subscript I Baseline EndFraction plus StartFraction d Subscript I Baseline over d Subscript o Baseline EndFraction. The inverse of f equals the inverse of d Subscript o Baseline minus the inverse of d Subscript I Baseline. The inverse of f equals the inverse of d Subscript o Baseline plus the inverse of d Subscript I Baseline.

The inverse of f equals the inverse of d Subscript o Baseline plus the inverse of d Subscript I Baseline.

Explanation:

The lens equation shows the relation among focal length of the lens, image distance and object distance. It can be expressed as:

  = +

where: f is the focal length of the lens, is the object distance to the lens and is the image distance to the lens.

The lens equation can be used to determine the unknown value among the variables f , and .
