WebOct 13, 2024 · The thin lenses have the yields of a negative distance of image, and the virtual images are on the same side as the object faced on the lens. The positive and negative sides of the images are useful to calculate the distance of the image in the real life as a lens equation. WebAppendix II-1: Thin Lens Combination The image position for two thin lenses is s i2 = f 2 d− f 2 s o1 f (s o1 −f) d−f 2 − s o1 f (s o1 −f 1) where s o is the position of the object (before either lens), and d is the distance between the lenses. If s o = ∞, and d=f 1+f 2, then s i = ∞. This is a Galilean telescope.
WebAug 13, 2014 · Using the thin lens equation the object distance is positive, unless using multiple lenses and the image of the object becomes the "virtual" object. In that case it will be a negative value. ( 3 votes) Show more... Harshika 6 years ago At 4:42 WebApr 7, 2024 · This means that the combination of lenses is replaced by a single lens having a focal length F and it forms the image at I when the object is placed at S. F is the focal length of the combination of lenses. The final equation of the combination of these lenses will hence be. 1 v − 1 u = 1 F.
