SUMMARY
The discussion clarifies the differences between the formulas for convex lenses and convex mirrors. The formula for convex mirrors uses a negative focal length, represented as 1/f = 1/do + 1/di, while convex lenses utilize a positive focal length. The established sign convention dictates that the focal length (f) is positive for concave mirrors and convex lenses, and negative for convex mirrors and concave lenses. This distinction is crucial for accurate optical calculations.
