Their radii of curvature and the refractive index of the material of the lens.
Besides the curvature of the lens, the refractive index of the material the lens is made of determines the focal length. The refractive index affects how light rays bend as they pass through the lens, ultimately determining the focal point.
The focal length of a lens is the distance between the lens and the image sensor when an object is in focus. It determines the field of view and magnification of the lens. A shorter focal length results in a wider field of view, while a longer focal length provides more magnification.
The distance between a lens and its focal point is called the focal length. This distance determines the magnification and the field of view of the lens. It is an important parameter in optical systems.
Focal length in a lens is the distance between the lens' optical center and the image sensor when the lens is focused at infinity. It determines the angle of view and magnification of the lens, with longer focal lengths resulting in a narrower angle of view and higher magnification, and vice versa. Focal length is commonly measured in millimeters.
The focal length of a convex lens is the distance between the lens and its focal point, where parallel rays of light converge after passing through the lens. It is a key parameter that determines the magnification and size of the image produced by the lens. The focal length is typically measured in millimeters.

The focal point is the point where light converges after it passes through a concave lens. The focal length is the distance of the focal point to the lens. Same for a convex lens, except that the focal point is the imaginary point from where light deflected from lens seems to have emerged.
The "mm" in a camera lens refers to the focal length of the lens, which determines the angle of view and magnification of the image.
The lens focal length formula used to calculate the focal length of a camera lens is: Focal Length (Distance between lens and image sensor) / (1 (Distance between lens and object) / (Distance between lens and object))
As the sides of a convex lens become less curved, the focal length increases. This change is due to the decreased curvature causing light rays to converge at a point farther away from the lens. The lens will have a weaker converging effect, resulting in a longer focal length.
It is called the focal length. It is equal to 1/2 times r, and is positive on concave mirrors and negative on convex mirrors.
The focal length of a zoom lens determines how much the lens can magnify distant objects and how versatile it is in capturing different types of shots. A longer focal length provides greater magnification for faraway subjects, while a shorter focal length allows for wider angles and more flexibility in composition.
The focal length of a camera lens determines its zoom capabilities. A longer focal length provides greater zoom, allowing you to magnify distant objects. Shorter focal lengths offer wider angles of view but less zoom.
