Rays passing through the principal focus or directed towards the centre of curvature play a crucial role in image formation. They demonstrate the reflective properties of mirrors, leading to the emergence of parallel rays or reflection along the same path, ...

The fact that a ray parallel to the principal axis in a concave mirror, after reflection, passes through the principal focus illustrates the focusing property of concave mirrors. This phenomenon is utilized in understanding image formation.

In a concave mirror, a ray passing through the centre of curvature is reflected back along the same path. Similarly, in a convex mirror, a ray directed in the direction of the centre of curvature is also reflected back along ...

A ray passing through the principal focus of a concave mirror, or directed towards the principal focus of a convex mirror, after reflection, emerges parallel to the principal axis.

In a concave mirror, a ray parallel to the principal axis, after reflection, passes through the principal focus. In contrast, in a convex mirror, the same ray appears to diverge from the principal focus after reflection.

The rays chosen for constructing ray diagrams are selected for their ease in determining their directions after reflection from the mirror. While an arbitrary number of rays could be considered, the chosen rays simplify the analysis and make it easier ...

The position of the image is determined by the intersection of at least two reflected rays. By choosing specific rays, it becomes possible to construct a clear ray diagram, and the point where these rays intersect gives the location of ...

The focal length (f) of a spherical mirror is the distance between the pole and the principal focus. It is represented by the letter f and provides a quantitative measure of the mirror’s ability to converge or diverge light rays.

In a convex mirror, rays parallel to the principal axis are reflected in such a way that they appear to diverge from a point on the principal axis. This point is known as the principal focus of the convex mirror, ...

The principal focus of a concave mirror is the point where all reflected rays, parallel to the principal axis, converge or intersect. This convergence of rays defines the principal focus and is represented by the letter F.
