Focal length of a concave mirror?
1/object distance + 1/ image distance = 1/focal length
If the surface of a concave mirror is made more curved what happens to its focal length?
A concave mirror is a spherical mirror with a reflective inside surface. When the reflective surface is made more curved, the distance between the focal point and the surface increases. A concave mirror can form both virtual or real images.
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 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.
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 distance from the center of a mirror to a focal point called?
The distance from the center of a mirror to the focal point is called the focal length.
What is the distance from the center of a mirror to the focal point called?
The distance from the center of a mirror to the focal point is called the focal length.
Which term defines the distance from the focal point to either a lens or a mirror?
The term that defines the distance from the focal point to either a lens or a mirror is called the focal length.
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 relationship between object distance image distance and focal length of a concave mirror?
In a concave mirror, the relationship between object distance, image distance, and focal length is described by 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. As the object distance changes, the image distance and focal length will also change accordingly.
Will focal length of mirror change on changing the object distance?
No, the focal length of a mirror does not change when the object distance changes. The focal length of a mirror is a fixed property of the mirror itself. Changing the object distance will affect the position and size of the image formed by the mirror, but not the focal length.
What will the object distance be equal to when using concave mirror only?
When using a concave mirror, the object distance (distance of the object from the mirror) can vary depending on where the object is placed. If the object is located beyond the focal point of the mirror, the object distance will be positive. If the object is placed between the mirror and the focal point, the object distance will be negative.
Which term indicates the distance between the surface at the center of a reflective surface and the focal point aplus answer?
The term you are referring to is the focal length, which is the distance between the surface of a reflective surface (such as a mirror) and the focal point.
What is the distance between a lens and its focal point is called?
The distance between a lens and its focal point is called the focal length. This distance determines the magnification and the field of view of the lens. It is an important parameter in optical systems.
What is the relationship between object distance image distance and focal length of concave mirror?
Sum of reciprocal of object distance and reciprocal of image distance gives the reciprocal of focal length
What is distance between mirror or lens and place where light rays meet?
Focal point
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.
