WebIt is an equation that relates the focal length, image distance, and object distance for a spherical mirror. It is given as, 1 i + 1 o = 1 f. i= distance of the image from the lens. o= distance of the object from the lens. f= focal length of the lens. The lens formula is applicable to all situations with appropriate sign conventions. Webf = focal distance = 28 mm di = image distance = 29 mm do = object distance = what we want to find So, that gives us: 1/do + 1/29 = 1/28 1/do = 1/28 - 1/29 1/do = 1/ 812 do = …

WebF-ratio. In photography there’s a handy number used to describe the relationship between lens diameter and focal length: the “f-ratio”. Simply put the f-ratio is the focal length divided by the diameter. In Fig 1.3.1 above we have a lens with a focal length of 50mm and a diameter of 10mm. 50/10=5 which gives us an f-ratio of 1/5 or f5.
