SUMMARY
The refractive index of a plano-convex lens can be calculated using the lensmaker's equation: 1/f = (n-1)(1/r1 - 1/r2). Given a focal length (f) of 0.2 m, a radius of curvature (r1) of 0.07 m for the convex side, and an infinite radius of curvature (r2) for the flat side, the refractive index (n) can be determined. Substituting these values into the equation allows for the calculation of n, which is essential for understanding lens optics.
