Focal length equation thin lens
WebApr 4, 2024 · Lens equation or lens formula is an equation that relates the focal length, image distance, and object distance for a spherical mirror. It is given as, Lens Formula - 1/u + 1/v = 1/f where. v = Distance of the image from the lens. u = Distance of the object from the lens. f = Focal length of the lens. WebI have found the formula for the effective focal length f of two thin lenses with focal lengths f 1 and f 2 separated by distance d to be 1 f = 1 f 1 + 1 f 2 − d f 1 f 2. However, I …
