Sum of focal length and radius of curvuture is 30cmWhat is the focal length of this spherical 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.
What is the focal length of concave mirror of radius 20cm?
The focal length of a concave mirror is half of its radius of curvature. Therefore, for a concave mirror with a radius of 20 cm, the focal length would be 10 cm.
The relation between focal length and radius of curvature of spherical mirror is?
The relation between focal length (f), radius of curvature (R), and the focal point of a spherical mirror can be described by the mirror equation: 1/f = 1/R + 1/R'. The focal length is half the radius of curvature, so f = R/2.
What distance along the axis from the center of a mirror to a focal point?
The distance from the center of a mirror to the focal point is equal to the focal length of the mirror. This distance is half the radius of curvature of the mirror.
What is the focal length of concave mirror to form real image?
The focal length of a concave mirror to form a real image is positive. It is equal to half the radius of curvature (R) of the mirror, and the image is formed between the focal point and the mirror.
What is the relation between focal length and center of curvature?
The focal length of a concave mirror is about equal to half of its radius of curvature.

What is the exact relation of the focal length to the center of curvature?
The focal length (a.k.a focus) is exactly half the length of the centre of curvature. ie. F = 1/2 C
What distance along the axis from the center of a mirror to a focal point?
The distance from the center of a mirror to the focal point is equal to the focal length of the mirror. This distance is half the radius of curvature of the mirror.
What is the focal length of concave mirror to form real image?

For very small angles the focal length of a concave mirror is?
For very small angles, the focal length of a concave mirror is approximately half of the radius of curvature of the mirror. This is known as the mirror equation and holds true for small angles under the paraxial approximation.
Can a square be cut in half vertically to make two identical rectangles?
Yes of course. Each rectangle will have a width half its length.
How do you derive relation between focal length and radius of curvature of convex mirror?
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.
What is the ratio of focal length of a spherical mirror to its radius curvature?
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.
