Focal length thick lens equation
WebJul 6, 2010 · The t = 0 assumption gave the thin lens an optical power approximately equal to that of the thick lens. These equations were developed in order to solve paraxial optical relationships with analytical functions instead of ray tracing, resulting in a body of knowledge referred to as Gaussian optics. 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.
