What is the lens maker's formula and how is it used to calculate the focal length of a lens?
The lens maker's formula is a mathematical equation used to calculate the focal length of a lens based on its refractive index and the radii of curvature of its surfaces. It is expressed as:
1/f (n - 1) (1/R1 - 1/R2)
Where: f focal length of the lens n refractive index of the lens material R1 radius of curvature of the first lens surface R2 radius of curvature of the second lens surface
By plugging in the values for n, R1, and R2 into the formula, one can determine the focal length of the lens.
