What is the focal length of a double convex lens for which the radius of curvature of each surface is 30 cm and the refractive index of glass is 2.50 ?
Here given Surface curvature (R ) = 30 cm., Refractive index (n) = 2.50 For a double convex lens, R = −1R1 1/f = (n-1) {1/(R1 - R2)} => 1/f = (2.5 - 1) {1/30 + 1/30} => 1/f = 1/10 => f = 10 cm Hence, the focal length of a double convex length is 10 cm.
