Webb1 do = 0.0333 1 d o = 0.0333. Multiply both sides by do d o and divide both sides by 0.0333 0.0333 to get do d o on its own. 1 0.0333 = do 1 0.0333 = d o. do = 30cm d o = 30 c m. Example 3. A nail is placed a distance of 40cm 40 c m from a diverging lens and an image is produced at a distance of 10.91cm 10.91 c m from the lens. WebbTo determine the image distance, the lens equation must be used. The following lines represent the solution to the image distance; substitutions and algebraic steps are shown. 1/f = 1/do + 1/d i 1/ (15.2 cm) = 1/ (45.7 cm) + 1/d i 0.0658 cm -1 = 0.0219 cm -1 + 1/d i 0.0439 cm -1 = 1/d i di = 22.8 cm WebbTo derive this formula we use the following sign conventions. 1. All distances are measured from the optical center of the lens. 2. Real distances are taken as positive and virtual distances are taken as negative. 3.

WebbA thin lens is defined as one whose thickness is insignificant in comparison to its curvature radii. The thickness (t) is significantly lower than the two curvature radii R 1 and R 2. The focal length, image distance, and object distance are all connected in the lens formula for concave and convex lenses. Webb15 jan. 2024 · f = 1 P = 1 − 0.5D = − 21 D = − 2m.
