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.
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.
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.
What is 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.
What is a concave mirror has a radius of curvature of 40.5 cm. how far is the mirror from the persons face?
The focal length of a mirror with a radius of curvature of 40.5 cm is half of the radius, so it is 20.25 cm. The mirror's face would be placed around this focal length distance from the person's face for optimal viewing.
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.
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.
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.
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 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.
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.
What is a concave mirror has a radius of curvature of 40.5 cm. how far is the mirror from the persons face?
The focal length of a mirror with a radius of curvature of 40.5 cm is half of the radius, so it is 20.25 cm. The mirror's face would be placed around this focal length distance from the person's face for optimal viewing.
How can a rough value of the focal length of a concave mirror be obtained?
One way to estimate the focal length of a concave mirror is to use the mirror formula: 1/f = 1/do + 1/di, where f is the focal length, do is the object distance, and di is the image distance. By measuring the object distance and the corresponding image distance, you can calculate an approximate value for the focal length of the concave mirror.
Will focal length of a concave mirror would increase decrease stay the same if the mirror were made flatter?
If a concave mirror is made flatter, its focal length will increase. This is because a flatter mirror has a larger radius of curvature, resulting in light rays converging at a point farther away from the mirror.
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.
How do you find focal length of concave mirror?
The focal length of a concave mirror can be found by using the mirror formula, which is 1/f = 1/do + 1/di, where f is the focal length, do is the object distance, and di is the image distance. By measuring the object and image distances from the mirror, you can calculate the focal length using this formula.
