Focal length and refractive index relation
WebNov 8, 2024 · It is important to note that if we dig into the details hidden within the variable f, we find that for spherical mirrors the focal length is a simple function of the radius ( f = R 2 ), while for lenses the focal length comes from the lensmaker equation (two radii and an index of refraction). Webf = focal length. • ( 5 votes) santhosh prabahar 5 years ago If 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 conventions.
