The focal length of a convex mirror is half of its radius of curvature.
The center of curvature of a spherical mirror is the point at the center of the sphere from which the mirror is a part. It is located at a distance equal to the radius of the sphere. The center of curvature is an important point for determining the focal length and the magnification of the mirror.
If the sum of the focal length and radius of curvature is 30cm for a spherical mirror, then the focal length is half of this sum, which would be 15cm.
In a concave mirror, the radius of curvature is twice the focal length.
The curvature of the eye's lens is related to its focal length: a more curved lens will have a shorter focal length, which allows the eye to focus on near objects. Conversely, a less curved lens will have a longer focal length, allowing the eye to focus on distant objects.
For a convex mirror, the focal length (f) is half the radius of curvature (R) of the mirror. This relationship arises from the mirror formula for convex mirrors: 1/f = 1/R + 1/v, where v is the image distance. When the object is at infinity, the image is formed at the focal point, and the image distance is equal to the focal length. Hence, 1/f = -1/R when solving for the focal length in terms of the radius of curvature for a convex mirror.
The focal length of a concave mirror is about equal to half of its radius of curvature.
The Center of curvature is 2 times the focal length. By the way this is a physics question.
f=|-R/2|
The focal length (a.k.a focus) is exactly half the length of the centre of curvature. ie. F = 1/2 C
The center of curvature of a spherical mirror is the point at the center of the sphere from which the mirror is a part. It is located at a distance equal to the radius of the sphere. The center of curvature is an important point for determining the focal length and the magnification of the mirror.
If the sum of the focal length and radius of curvature is 30cm for a spherical mirror, then the focal length is half of this sum, which would be 15cm.
The focal point of a convex mirror lies on the same side as the centre of curvature and is at a distance of half the radius of curvature from the optical centre.
In a concave mirror, the radius of curvature is twice the focal length.
The curvature of the eye's lens is related to its focal length: a more curved lens will have a shorter focal length, which allows the eye to focus on near objects. Conversely, a less curved lens will have a longer focal length, allowing the eye to focus on distant objects.
