Question

Explain:-
Center of Curvature
Radii of Curvature
Principal Axis​

Answer 1

Answer:

1) Centre of curvature: It is the centre of sphere of which the surface of the lens is a part. 2) Principal axis: It is the line passing through the optical centre of the lens and perpendicular to both the faces of lens. 3) Optical centre: It is the geometrical centre of the lens

Answer 2

To explain the following term:

1. Center of Curvature
2. Radii of Curvature
3. Principal Axis

Answer:-

1. Center of Curvature: The centre of two spheres of which the two surfaces of the given lens are the part are called as Center of Curvature.

2. Radii of Curvature: The radii of two spheres in which lens surfaces are a part are called Radii of Curvature.

3. Principal Axis: The line that joins the center of Curvature of the two surfaces of a lens is called Principal Axis.
