In a plane mirror, the radius of curvature is infinitly long, so the focus will be at infinity. Another way to say it is that a plane mirror has no curvature, and as curvature becomes increasingly small, focal length becomes increasingly long. At a curvature of zero, focal length becomes infinite.
Focal length(f) is given by f=R/2 where R is radius of curvature..
Once again, it's infinity! See answer to your question on radius of curvature. Plug infinity (radius of curvature) into your mirror equation to get the focal length, which will also be infinite. A flat mirror does not focus incoming parallel beams.
That's because if you say its at infinity it means it does exist in a finite
distance, that is instead of saying it does exist its taken at infinite distance for only theoretical importance and not for practical observance. Focal length is half of radius of curvature of the mirror. So bigger the circle gets the more its radius will be. So in the same way as the curvature of the sphere gets less and less its focal length increases, so
when it becomes totally flat the focal length will become infinite so it means it has no existence but it has only theoretical importance.
It same as taking the formation of image of an object at principal focus to be at infinite distance rather than saying it does not form ( that is both mean the same).
hope my answer is satisfactory
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.
Infinity.because the distance of object from mirror"p" and the distance from image to mirror"q" are equal,so by using formula1/f=1/p+1/qwe can find the answeras the image of plane mirror is virtual,so"q" is taken negative,so putting values1/f=1/p-1/p(bcz p=q)1/f=0f=1/0and any thing divided by zero is infinity.hope this helps
Yes, the mirror formula, 1/f = 1/do + 1/di, holds for plane mirrors as well. In the case of a plane mirror, the focal length (f) is considered infinite. This means that the distance of object (do) is equal to the distance of the image (di), but in opposite directions.
The back focal length in optical systems is important because it determines the distance between the rear focal point of a lens or mirror and the focal plane where an image is formed. This distance affects the magnification, field of view, and overall performance of the optical system.
No, it will not, this is because a plane mirror has no focal point. It's rays never converge at a single point like a concave mirror, and therefore it has no focal point The mirror equation is 1/f=1/di + 1/do, where f is the focal point, di is the distance of the image from the mirror, and do is the distance of the reflected object from the mirror. Since focal point is required for the equation, it can't work. Hope this helps.
Focaal length for plane mirror is 0

it is zero . Power = 1/focal length The focal length of a plane glass or mirror is infinite, therfore power is zero

The focal length of a plane is a fixed distance that defines its curvature or orientation. It does not change and can be specified by the designer or manufacturer. To find the focal length of a plane, refer to the technical specifications provided by the manufacturer or measure it directly using optical tools such as a focal length tester.

By increasing its radius of curvature to infinity.

Plane mirrors don't have one, I'd say it was 0.

A plane mirror is flat, so your image is the same size as you. A spherical mirror is curved. If concave it can be used either to focus an image as in a reflecting telescope, or magnify as in a shaving/makeup mirror. If convex you get a smaller wide-angled image, as in a car's wing mirror
