SUMMARY
The focal length of a Plano-Convex lens is determined using the lens maker's equation, which applies regardless of whether light passes through the convex side or the planar side. Calculations using R1 for the convex side and R2 for the plane side yield the same focal length as calculations using R1 for the plane side and R2 for the convex side. The key takeaway is to carefully consider the signs in the lens maker's equation, as they can affect the calculations but do not change the final result.
