Question

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.

Answer 1

`D. (1)/(f) = (1)/(d_(0) ) + (1)/(d_(i) )~~`

Step-by-step explanation:

Answer 2

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

Step-by-step explanation:

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

`(1)/(f)` =
`(1)/(d_(o) )` +
`(1)/(d_(I) )`

where: f is the focal length of the lens,
`d_(o)` is the object distance to the lens and
`d_(I)` is the image distance to the lens.

The lens equation can be used to determine the unknown value among the variables f ,
`d_(o)` and
`d_(o)`.
