mirror
1- focal point and focal length
mirrors are occasionally used in placed of lenses in optical instrument ,but their application . are not so broad as those of lenses because they don t after the same possibilities for correction of the other aberration of the image .
the point F called the focal point and the distance FA the focal length.
F =-R/2
if the mirror is concave R is negative quantity , F is positive and the the first focal point lies at the lift of the vertices , half way between it and the center of curvature .

the second focal point of surface design F is defined as the image an infinity distance object point on the axis that is , it is the point at which incident rays originally parallel to the axis intersect after reflection or refraction
the second the distance from the vertex to the second point p is the second focal length if we set s=
if the mirror is concave R is negative s and F are negative also and since they refer to image distance , the second FPlies distance R/2 to the left of the vetting as in fig . in other words the first and second Fl of mirror and equal and the first and second F.P of mirror Coincide the focal point of a mirror is considered to be the first Fl .ocal point and focal length
