significance of lens marker's formula
Answers
Answer:
The focal length of a lens depends on the refractive index of the lens and the radii of curvature. The lens maker's equation is another formula used for lenses that give us a relationship between the focal length, refractive index, and radii of curvature of the two spheres used in lenses.

The Lens Maker’s Equation for Thin Lenses:
1f = (n−1)(1R1 − 1R2)
where,
f is the focal length (half the radius of curvature)
n is the refractive index of the material used
R1 is the radius of curvature of sphere 1
R2 is the radius of curvature of sphere 2
