Webb6 apr. 2024 · Now solve this equation to find the focal length of the lens. Square on both sides, we get ⇒ d 2 = D 2 − 4 f D ⇒ 4 f D = D 2 − d 2 ∴ f = D 2 − d 2 4 D This is the required value of focal length for convex lens by displacement method. This …
Webb10 jan. 2016 · We are assuming a thin lens in this formula, so the diameter of the lens must be small compared with R. If the focal length is 30 cm and the diameter of the lens is 1 cm the thickness is twice the height of a circular segment. Given R = 30, c = 1 we have h = R − R 2 − ( c 4) 2 = 30 − 900 − 1 4 ≈ 0.004 so the lens is about 1 mm thick Share Cite

The distance between the pole of the mirror ( or the optical center of the lens) and the focal point of a mirror (or lens) is called the focal length. The focal point (F) of a mirror is the point at which a parallel beam of light is "focussed" after reflection in the mirror.
