Infinity.because the distance of object from mirror"p" and the distance from image to mirror"q" are equal,so by using formula
1/f=1/p+1/q
we can find the answer
as the image of plane mirror is virtual,so"q" is taken negative,so putting values
1/f=1/p-1/p(bcz p=q)
1/f=0
f=1/0
and any thing divided by zero is infinity.

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.
Focal length of a concave mirror?
1/object distance + 1/ image distance = 1/focal length
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 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.
Is the focal length equal to the radius of curvature of the mirror?
yes
What is a focal length of a plane mirror?
Focaal length for plane mirror is 0
What is power of plane glass sheet?
it is zero . Power = 1/focal length The focal length of a plane glass or mirror is infinite, therfore power is zero
What is the power of a plane mirror?
A plane mirror has the power of creating images that are virtual, upright, and the same size as the object being reflected. It does not alter the size or shape of the object, but simply reflects light rays.
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.
Why does the focal length of a mirror not depend on the mirror material when the focal length of a lens does depend on the lens material?
The focal length for a mirror is determined by the law of reflection from the mirror surface. This law is not governed by the material that the mirror is made by. This means that the focal length depends only on the radius and curvature. Conversely, the focal length of a lens depends on the indices of refraction of the lens meterial and the surrounding medium.
What is the focal length of a telescope's mirror if I use an eyepiece with a focal length of 26 mm and I get a magnification of 70x?
The focal length of the telescope's mirror can be calculated using the formula: Telescope focal length = Eyepiece focal length × Magnification = 26 mm × 70x = 1820 mm Therefore, the focal length of the telescope's mirror would be 1820 mm.
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.
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.
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 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.
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.
