What is the relationship of magnification with focal length of a spherical mirror?
m = f-v/f = f/f-u.
What is Bar relationship of magnification with the focal length and distance of image?
m=ff−u.
What is the relationship between the focal length of a cylindrical mirror and its radius of curvature?
A concave cylindrical mirror focuses incoming parallel rays at its focal point. The focal length ( f) is the distance from the focal point to the cen- ter of the mirror surface. The radius of curvature (R) of the mirror is twice the focal length.
What is the difference between magnification and magnifying power?
What is the difference between Magnification and Magnifying power?…1 Answer.
| Magnification | Magnifying power |
|---|---|
| (i) It is a linear magnificant which (is equals to h2/h1). | (i) It is an angular magnification which is equals to ∠β/∠α |
What determines the magnification of a lens?
The magnification can be found by taking the ratio of the image distance to the object distance. If you want to make your source or object larger, with a magnification greater than 1, the lens must be closer to your object than the image, since image distance must be greater than your object distance.
What is the relationship between focal length image distance and object distance for Convex?
As the object distance approaches one focal length, the image distance and image height approaches infinity. Finally, when the object distance is equal to exactly one focal length, there is no image.
What is magnification give its formula for spherical mirror and spherical lens?
It is the ratio of the height of the image to the height of the object and is denoted as m. The magnification, m produced by a spherical mirror can be expressed as: m=h′h where h′ is height of image and h is height of object. It is also equal to the negative of the ratio of the image distance(v) to object distance (u).
What is the relationship between focal length image distance and object distance?
Object distance means what is the distance between pole and object. Image distance means when image is formed then the distance between pole and image is called image distance. Focal length is the distance between pole and the principal focus of the mirror.
How does magnification change with the object distance?
When the object and image are the same distance, the magnification is 1 and the image distance happens to be twice the focal length (2f), but this changes when you move the object closer or farther away from this point.
What is the focal length of the mirror?
The focal length ( f ) is the distance from a lens or mirror to the focal point ( F ). This is the distance from a lens or mirror at which parallel light rays will meet.
Does the focal length of a spherical mirror depend on the nature of medium in which mirror is placed?
Focal length mainly depends on one factor: Radius of curvature R of the spherical mirror. If the mirror is in air or in another medium, then focal length = R/2. Focal length is independent of the medium, material of the mirror, frequency of the light rays, temperature etc.
What is the relationship between magnification and focal length?
Where real images are involved, there is no direct relationship to magnification and focal length. Magnification of the image compared to the object can be calculated by the ratio of object and image distance, but this number can vary anywhere below 1 or above one.
What is the magnification of a spherical mirror?
The magnification produced by a spherical mirror gives a relative extent to which the image formed by an object is magnified with respect to the size of the object. A negative sign in the value of the magnification denotes that the image is real, while a positive sign in the value of the magnification denotes that the image is virtual.
What is the difference between magnification andmirror formula?
Mirror formula is applicable for all spherical mirrors for every position of the object. Magnification is the increase in the image size produced by spherical mirrors with respect to the object size. It is the ratio of the height of the image to the height of the object and is denoted as m.
What is the magnification when the object and image are the same?
When the object and image are the same distance, the magnification is 1 and the image distance happens to be twice the focal length (2f), but this changes when you move the object closer or farther away from this point.
