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 the power of a plane mirror?
Power is ZERO Since power = 1/ focal length As focal length of plane mirror is infinity, its reciprocal 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
How can a rough value of the focal length of a concave mirror be obtained?
rough focal length of concave mirror
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.
Why do images in a concave mirror appear inverted?
If an object's distance from the concave mirror is greater than the mirror's focal length, then the mirror image of it will be inverted. If the distance from the concave mirror is less than the focal length of the mirror, the image will not be inverted. No image will be produced if the distance from the mirror to the object is equal to the mirror's focal length.
The relation between focal length and radius of curvature of spherical mirror is?
The focal length of a convex mirror is half of its radius of curvature.
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.
How tall mirror do you need to see your body full length?
That will depend upon your focal length--how far your eye is from the mirror. At a useful focal length the mirror can only be a few inches shorter than the subject.
What is the defition for plane flat mirror?
A plane flat mirror, as opposed to a concave or convex mirror, is flat and therefore has no focal point. Think of the mirror in your bathroom.
Focal length of a concave mirror?
1/object distance + 1/ image distance = 1/focal length
Which term defines the distance from the focal point to either a lens or a mirror?
focal length
