Question

In the Lens Maker's Formula, the symbols \[R_1\] and \[R_2\] denote:

विकल्प

• The radii of curvature of the first and second surfaces of the lens

• The object distance and image distance

• The heights of the object and the image

• The refractive indices of the lens and the surrounding medium

Answer 1

In the Lens Maker's Formula, \[R_1\] is the radius of curvature of the first surface and \[R_2\] is the radius of curvature of the second surface of the lens. These, along with the refractive index \u03bc, determine the focal length f of the lens.
