Question

What is the difference between lens formulae and lens maker formulae

Answer 1

Answer:

Explanation:

Using the positive optical sign convention, the lens maker's formula states

(1/f) = (n-1) {(1/R1) + (1/R2)}

where f is the focal length, n is the index of refraction, and R1 and R2are the radii of curvature of the two sides of the lens.

Whereas the in the case of lens formula ,

(1/f) = (1/v) - (1/u)

where f is the focal length and v and u are the Image and Object Distances

• For a thin lens, the lens power of lens P For a thin lens is the sum of the surface powers but, for the thicker lenses, Gullstrand's equation can be used to get the equivalent power.
