Answers
Explanation:
Define the following terms in the context of spherical mirror- (i)principal axis
the line passing through centre of curvature, focus ,pole
(ii)centre of curvature center of sphere
(iii)principal focus where all reflected rays meet
Answer:
a line passing through the center of the surface of a lens or spherical mirror and through the centers of curvature of all segments of the lens or mirror. Physics.
the centre of a circle which passes through a curve at a given point and has the same tangent and curvature at that point.
In geometrical optics, a focus, also called an image point, is the point where light rays originating from a point on the object converge. Although the focus is conceptually a point, physically the focus has a spatial extent, called the blur circle.
