how does focal length influence the refraction of light? explain
Asked by | 30th Jan, 2012, 10:30: PM
1/f =(?-1)(1/R1 -1/R2)
here, f= focal length of the lens.
R1,R2=radius of curvature of two faces of the lens
so if the refractive index of the material opf the lens is more then the focal length will be less. ie light will bend more.
