WebThe radii of curvature here are measured according to the Cartesian sign convention. For a double convex lens the radius R 1 is positive since it is measured from the front surface and extends right to the center of curvature. The radius R 2 is negative since it extends left … WebFormula of the Radius of Curvature. Normally the formula of curvature is as: R = 1 / K’. Here K is the curvature. Also, at a given point R is the radius of the osculating circle (An imaginary circle that we draw to know the radius of curvature). Besides, we can sometimes use symbol ρ (rho) in place of R for the denotation of a radius of ...
WebThe radius of curvature of a curve y= f (x) at a point is (1 +(dy dx)2)3/2 d2y dx2 ( 1 + ( d y d x) 2) 3 / 2 d 2 y d x 2 . It is the reciprocal of the curvature K of the curve at a point. R = 1/K, where K is the curvature of the curve and R = radius of curvature of the curve. How Do … WebFinal answer. Step 1/1. solution: Explanation: To solve this problem, we can use the lens maker's formula which relates the focal length of a lens to its refractive index and radii of curvature of its surfaces. The formula is: 1 f = ( n − 1) × ( 1 R 1 − 1 R 2 + ( n − 1) × d n × R 1 × R 2) where f is the focal length of the lens, n is ...

Our goal was ... WebAnalytically, the focal length is described by the lens maker's equation: 1/f = (n - 1)(1/R 1 + 1/R 2), where R 1 and R 2 are the radii of curvature, f is the focal length, and n is the index of refraction. Verify that your earlier measurements are consistent with this equation.
WebIf you did this problem using the equation 1/f=1/v-1/u, you would get the answer as 6 cm. According to the same sign convention using which the above mentioned formula was derived, the answer 6 cm means the same as -6 cm when viewed from different sign …
