Divergent lens focal length

WebThe lens formula is used to identify the nature and the position of the image formed by the concave lens. The lens formula is expressed as follows: 1 f = 1 v + 1 u. where f is the focal length, v is the distance of the image … WebIt can be shown that the lens focal length is related to the distance between different Moiré images. According to the author, this method gives the focal length value with less than 1% accuracy. 7. Fizeau interferometry The length focal length is calculated using the following formula: 1 6 + 1 7 = 1 U and V are measured from the principal planes.
