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.
If the focal lenght of a concave mirror is 15 cm find the radius of curvature?
The radius of curvature and the focal length mean the same so the radius of curvature is also 15 cm.
Why the focal length of concave mirror changes in water?
I don't think so. The focal length would remain the same. It mainly depends on the radius of curvature of the mirror.
What is the Focal length of a concave mirror?
It is the point , on the central axis, where light, that is parallel to the central axis, passes thru after it is reflected from the mirror. It is also at a distance from the mirror equal to twice the radius of curvature of the mirror.
The distance between a mirror and its focal point is called the?
Focal length, positive number with a concave mirror, negative for a convex 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 relationship between the radius of curvature and focal length in a concave mirror?
In a concave mirror, the radius of curvature is twice the focal length.
A candle is placed between the center of curvature and the focal point of a concave mirror?
The image formed by the concave mirror will be located beyond the center of curvature, inverted, and smaller in size.
What are the parts of concave mirror?
The main parts of a concave mirror are the pole (center point), principal axis (imaginary line passing through the pole and center of curvature), focal point (half the distance between the pole and center of curvature), and the center of curvature (center of the sphere from which the mirror is a section).
WHAT HAPPENS TO THE FOCAL LENGTH OF A CONCAVE MIRROR AS THE CURVATURE OF THE MIRROR IS INCREASED?
As the curvature of a concave mirror is increased, the focal length decreases. This means that the mirror will converge light rays to a focal point at a shorter distance from the mirror. The mirror will have a stronger focusing ability.
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.
What is the significance of the center of curvature in a concave mirror?
The center of curvature in a concave mirror is important because it is the point where the mirror's surface is perfectly curved. Light rays that are parallel to the mirror's principal axis and strike the mirror will either converge or diverge at this point, depending on the mirror's shape. This point helps determine the focal length and image formation in concave mirrors.
What Is the focal point of a concave mirror?
The focal point of a concave mirror is the point where parallel rays of light converge or appear to converge after reflection. It is located half the distance between the mirror's surface and its center of curvature. This focal point is a key element in determining the mirror's magnification and imaging properties.
What are the rules in concave mirror?
In concave mirrors, light rays that are parallel to the principal axis converge at the focal point. The rules for concave mirrors include: 1) light rays passing through the focal point reflect parallel to the principal axis, 2) light rays reflecting off the mirror pass through the center of curvature, and 3) the distance from the focal point to the mirror is half the radius of curvature.
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 can you infer about the focal point of the mirror?
The focal point of a concave mirror is the point where parallel rays of light converge after reflecting off the mirror. It is located halfway between the mirror's surface and its center of curvature. This focal point is an important property that determines the mirror's ability to form images.
What is the nature of the image produced by a concave mirror if the object lies beyond twice of focal length?
If the object lies beyond twice the focal length of a concave mirror, a real and inverted image is produced between the focal point and the mirror's center of curvature. The image is diminished in size compared to the object.
