No such term vertex being used in concave mirror. We would say by the term 'pole' of the mirror.
Or optic center of the mirror.
Of course vertex is used in case of parabola. Following this we may use vertex synonym to the pole or optic centre of the concave mirror
Parallel light rays hitting a concave mirror will converge to a single focal point after reflection, due to the mirror's inward or converging shape. The focal point is located on the principal axis of the mirror, halfway between the mirror's center and the vertex. This property of concave mirrors is used in applications like focusing light in telescopes and for creating images in reflective devices.
Concave
The focus of a concave mirror is the point where parallel rays of light converge after reflecting off the mirror. It is located along the principal axis, halfway between the vertex and the center of curvature of the mirror. Rays of light that are parallel to the principal axis will reflect and converge at the focus.
A concave mirror is a curved mirror that curves inward. In a ray diagram for a concave mirror, parallel rays of light that hit the mirror will converge at a point known as the focal point. One characteristic of the image formed by a concave mirror is that it can be real or virtual depending on the object's distance from the mirror.
Distance from the mirror, curvature of the mirror.
no concave mirror is in shape of concave mirror
why do we use concave mirror as converging mirror
Parallel light rays hitting a concave mirror will converge to a single focal point after reflection, due to the mirror's inward or converging shape. The focal point is located on the principal axis of the mirror, halfway between the mirror's center and the vertex. This property of concave mirrors is used in applications like focusing light in telescopes and for creating images in reflective devices.
Concave
Inner curved surface is known as concave mirror because inner side of the spherical mirror is polished to reflect the light is called concave mirror,and concave mirror is know because concave mirror converges parallel beam of light.
Such a mirror is concave.
A concave mirror would focus the light back towards the focal point of the mirror. You would not be able to use the mirror effectively with a concave.
Concave
concave mirror is a solar device
The focus of a concave mirror is the point where parallel rays of light converge after reflecting off the mirror. It is located along the principal axis, halfway between the vertex and the center of curvature of the mirror. Rays of light that are parallel to the principal axis will reflect and converge at the focus.
A "concave" mirror curves inward. A "convex" mirror curves outward.
