SUMMARY
The discussion centers on applying the Lensmaker's Formula to determine the image distance of a lens with a focal length of 20 cm and an object distance of 50 cm. The correct calculation yields an image distance of i = 100/3 cm. The user initially expresses confusion regarding the application of the formula, specifically questioning the validity of the derived image distance in the context of the equation 1/f = 1/o + 1/i. The resolution confirms that the calculation is accurate, reinforcing the understanding of lens optics.
