Radius of curvature in concave mirror
Did you know?
WebLet us now consider a spherical mirror of radius of curvature R, whose inner, concave surface is mirrored and faces the incident light, as in Figure 3. This is known as a concave mirror. The point C is the center of curvature of the mirror, the horizontal line through the vertex of the mirror is called the principal axis (or optical axis). WebThe radius of curvature: It is the radius of the sphere of which the mirror forms the part. It is represented by R. P C = R Principal axis: The straight line joining the pole (P) and the centre of curvature. It is normal for the mirror at its pole. Aperture: The diameter of the spherical mirror is called its aperture.
WebWhat kind of mirror must be used and what must its radius of curvature be? Solution: do = 2.00cm, m = 4.0 di = mdo, f = dodi do +di = do (mdo) do mdo = mdo 1 m = 4 2.00 1 4 cm = 2.67cm r = 2f = 5.3cm. Because the focal length is positive, the mirror is concave.
