Question

define the centre of curvacture.

don't copy and spam plzz

give my another physics question related to magnification plzz see this question in my questions box.​

Answer 1

Centre of curvature is the centre of the sphere from which the lens is made.

In simple words,

We know, that the lenses either concave or convex is a part of a sphere. The spheres must have a centre right? So, this centre of sphere is known as centre of curvature. There are two centre of curvatures in lens cause obviously the lenses are part of two spheres.

The attachment is an example for convex lens.

Cheers!

Answer 2

Answer:

DEFINATION OF CENTER OF CURVATURE :

Explanation:

The center of the circle whose center lies on the concave side of the curve and whose radius is equal to the radius of curvature of that point.

Hope it helps❤️
