A concave mirror, also known as converging mirror, is characterised by its inwardly curved reflecting surface which causes all parallel rays of light incident on it to converge at a single point after reflection, known as the focal point.

In concave mirrors, shorter focal length leads to large magnification, suitable for telescopes, while a longer focal length allows a larger field of view. Conversely, in convex mirrors, shorter focal lengths provide a wider field of view, which is ideal for car rearview mirrors.

A Convex Spherical Mirror is a mirror with a reflecting surface that bulges outward. It diffuses light outward, causing the rays to diverge or spread out. The convex mirror is also known as the diverging mirror.

A concave spherical mirror has a surface that caves inward and deviates light inward. A convex spherical mirror, on the other hand, has a surface that bulges outward and diffuses light outward.

The two essential formulas are the mirror equation: 1/f = 1/do + 1/di, and the magnification equation: m = -di/do, where f is the focal length, do is the object distance, di is the image distance, and m is the magnification factor.

FOV is specified in one of two ways: angular field of view and sized field of view (object size at a specific working distance).

Field of view (FOV) is defined as the maximum area that a device can capture. The larger the field of view, the more data can be captured at one time, so it will require fewer images to capture an entire target.

A spherical mirror, as the name suggests, is a part of a spherical reflecting surface. These mirrors can be cut out from a glass sphere, and their reflecting surfaces can either be curved inward or outward.

A spherical mirror in physics is a part of a spherical reflecting surface. These mirrors can be cut out from a glass sphere, and their reflecting surfaces can either be curved inward or outward.

Convex mirrors are usually used as rear-view mirrors in vehicles for a wider field of view, concave mirrors are used in telescopes to focus light and they're also used in shaving and make-up mirrors for magnified images.

A Concave Spherical Mirror is a mirror with a reflecting surface that caves inward. It deviates light inward towards a common point, also known as the focal point. The concave mirror is also called converging mirror because parallel rays coming towards the mirror after reflection converge at a point.

The lens focal length and sensor size both factor into determining the FOV. Assuming the lens focal length is fixed, the larger the sensor, the larger the required FOV.

Though camera FOV can be measured horizontally, vertically, or diagonally, it is more commonly measured horizontally, as most sensors are rectangular. This measurement is typically expressed in millimeters.
