Hi.......
Ans. Because plane mirror can be considered as a Sperical mirror of infinite radius of curvature.
Focal length is half of radius of curvature and hence it is infinity.

The focal length can be defined as the measure of how strongly a lens or mirror strongly converge or diverge the incident light.
Explanation:
The plane mirror exhibit a focal length of infinity, this is due to the fact that the image is formed at an infinite distance, within the mirror.
The focal length of the plane mirror is half the radius of curvature. Thus it is infinity.
