WebThat's why it gave you this distance between lenses. The distance between lenses is 33 centimeters. So if the distance from this 1st lens is 18 well the difference has to be equal to this length. So 33 minus 18 is … WebThis type of system can be created with a pair of optical elements where the distance between the elements is equal to the sum of each element's focal length (d = f1+f2). ... Note the sign convention: a telescope with two convex lenses (f 1 > 0, f 2 > 0) produces a negative magnification, indicating an inverted image.

WebNov 16, 2015 · If you want some math, take a look at the thin lens equation, and apply it to the objective lens. f = focal length of the lens. o = distance from lens to object. i = distance from lens to image. Then the thin lens equation is: 1/f = 1/i + 1/o i = 1/ (1/f - 1/o) If o = … WebWe can calculate the distance where the image is produced by applying the formula for converging lenses: 1 x o + 1 x i = 1 f → x i = 1 1 f - 1 x 0 = 1 1 10 c m - 1 30 c m = 15 c … on the green dublin
