  • The formula used when a light ray enters a medium with refractive index n2 from a medium with refractive index n1 at a curved interface with a radius of curvatures n2 /v –n1 /u = (n2 - n1 )/R 
  •  A lens is formed when one medium is separated from another medium by two surfaces, one of which is curved. 
  •  Lens formula is 1/f =1/v – 1/u where is the focal length of lens, u isthe object distance and v isthe image distance. 
  •  Lensmaker’sformula is 1/f = (n-1)(1/R1 -1/R2 ) whereR1 andR2 are radii of curvature, n is the refractive index and f is the focal length.
