Question

2. What is radius of curvature of the lens?​

Answer 1

Answer:

Definition: Radius of curvature of lens is the radius of the hollow sphere of glass of which the lens is a part. Each lens has two radii of curvature. Focal length,Reractive index and radius of curvature are related by lens makers.- Definition: Where f=focal legth of lens.

Answer 2

Radius of curvature of lens is the radius of the hollow sphere of glass of which the lens is a part. ... From this formula we can say that focal length of lens is inversely proportional to refractive index of material of lens medium. i.e As Refractive index (m) increases focal length (f) of lens decreases
