Question

define and show on a diagram the following terms relating to a concave mirror aperture radius of curvature​

Answer 1

Aperture means diameter of concave mirror of a spherical mirror.
Radius of curvature is radius of sphere whose mirror forms a part.

Answer 2

Answer:

Concave Mirror:

If a hollow spherical is split into pieces and the exterior surface of each cut part is painted, the resulting mirror has its inner surface as the reflecting surface. This is referred to as a concave mirror.

Characteristics of Concave Mirrors

• When light hits the concave mirror's reflecting surface, it converges at a single point and reflects back. Because of this, it is often referred to as a converging mirror.
• Obtaining an enlarged, upright, and virtual image requires placing the concave mirror extremely close to the object.
• The size of the picture, however, decreases as the distance between the object and the mirror increases, creating a true and inverted image instead.
• The concave mirror's image might be little or large, and it can be real or virtual.

Aperture:

A concave mirror's aperture is the point at which light is actually reflected. It also specifies the mirror's size.

Radius of Curvature:

The radius of curvature of a concave mirror is twice the focal length of the concave mirror.
