where is the principle focus of a plain mirror?
The principle focus or focal point of a mirror is the point at which light that is incident parallel to the aixs comes together at a point. The focal point is in a plane perpendicular to the axis (parallel to the surface of a plane mirror) called the focal plane. Any parallel rays incident on the mirror surface come to focus in the focal plane. If the incident rays are even the slightest bit converging when they hit the mirror, they will come to focus between the focal plane and the mirror.chandubaba said:where is the principle focus of a plain mirror?
The principle focus of a plain mirror is the point at which all incident rays parallel to the principal axis converge after reflection.
The principle focus of a plain mirror can be determined by drawing a ray diagram and locating the point where all incident parallel rays intersect after reflection.
Yes, in a plain mirror, the principle focus is equal to the focal length, which is half the distance between the mirror and its center.
No, the principle focus of a plain mirror is always located in front of the mirror, along the principal axis.
The distance between the object and the mirror does not affect the principle focus in a plain mirror. It remains at the same location regardless of the position of the object.
