1.	2) With the help of suitable diagram explain the meaning of the following terms Spherical mirrors, Concave mirror, Convex mirror, Centre of curvature,Radius of curvature, Principal axis, Pole, Focus, Focal length.
Answer» The centre of reflecting surface. It is represented by LETTER P.Centre of Curvature: The centre of the SPHERE of which the mirror forms the part. Represented by "C".Radius of Curvature: The radius of the sphere of which the mirror forms the part. Represented by "R".Principal axis: The straight line JOINING the pole (P) and the centre of curvature. It is normal to the mirror at its pole.Focus: The point of the principal axis at which the rays parallel to principal axis MEET (concave mirror) or appear to meet (convex mirror) after reflection. Represented by F.Focal Length: The distance between the pole and the principal focus of a spherical mirror is CALLED focal length. Represented by f.Step-by-step explanation:i hope it will help
