# Determining the focal length of a concave mirror by locating centre of curvature

Why is the focal length of a spherical mirror half of its radius of curvature the pole of the mirror c is the centre of curvature focal length of a concave . The radius of curvature, r, is twice the focal length a concave shaving mirror has a focal length of 33 from the focal point b calculate the . The point at which the principal axis hits cuts the centre of the concave mirror is called the vertex v focal point/focus (f) the location of the focal point is determined by the following equation f= 1/2r this means that the focal point is half the distance of the radius , therefore it is half way between the centre of curvature and the vertex .

Show transcribed image text a concave mirror has a radius of curvature with absolute value 20 cm, find graphically the image of a real object in the form of an arrow perpendicular to the axis of the mirror at each of the following distances (a) 30 cm (b) 20 cm (c) 10 cm and (d) 5 cm check the construction by computing the image distances and lateral magnification of each image. Concave mirrors were silvered on since the focal point is the midpoint of the line segment adjoining the vertex and the center of curvature, the focal length . Best answer: for a spherical concave mirror (which is not an ideal reflector) the radius of curvature is twice the focal length the focal length is the distance from the mirror that parallel light.
