What is the middle portion of the mirror called?
Vertex (V)
Which point is the center of the sphere of which the curved mirror is a part?
Center of curvature (C)
What is the line drawn passing through the vertex and the center called?
Principal axis (P)
Which point is the point where the reflected rays meet?
Focus (F)
What are ray diagrams used to depict in the context of mirrors?

It forms a virtual and upright image
Study Notes
Mirrors and Images
- A plane mirror forms a virtual image.
Concave Mirrors
- The reflective surface of a concave mirror bulges towards the observer.
- When the object is placed beyond the center of curvature, a concave mirror forms a real image.
- A concave mirror can form an enlarged image depending on the position of the object.
Convex Mirrors
- When an object is placed in front of a convex mirror, the image formed is always virtual and smaller.
- A convex mirror produces a virtual image that is never real because the reflected rays spread out from the mirror.
- When the object is placed anywhere in front of a convex mirror, a virtual image is formed.
Mirror Structure
- The middle portion of the mirror is called the vertex.
- The center of the sphere of which the curved mirror is a part is called the center of curvature.
- The line drawn passing through the vertex and the center of curvature is called the principal axis.
- The point where the reflected rays meet is called the focal point.
- Ray diagrams are used to depict the path of light rays and the formation of images in the context of mirrors.
