Formula for refractive index

WebSep 15, 2024 · In this article, the formula for the refractive index, n n, of a material is discussed using a problem-solving strategy. According to the index of refraction formula, n=\frac {c} {v} n = vc, the index of refraction of any substance is always greater than or equal to one. This is because the speed of light in a medium is always less than c c. WebApr 8, 2024 · The lensmaker's equation is 1/f = (n − 1) ( 1/R1 − 1/R2 + (n − 1)d/ (n R1 R2)), where f is the focal length of the lens, R1 is the radius of the first surface, R2 is the radius of the second surface, and n is the refractive index of the lens.
