Web11. apr 2024 · The power of a lens is measured as the reciprocal of the focal length of the lens. Relation with focal length: A lens of less focal length produces more converging or diverging and is said to have more power. I.e., P = 1/ F According to the lens maker’s formula, 1/ F = (v - 1) ( 1 R 1 − 1 R 2 ) Since, P = 1/ F We get, P = (v - 1) ( 1 R 1 − 1 R 2 ) Web8. nov 2024 · The horizontal line that is perpendicular to and bisects the surface that causes reflection or refraction is called the optical axis.
