Question

what do you know about the terms give below related to the spherical mirrors a) pole b) centre of curvature c) magnification d) facial lenght​

Answer 1

Answer:

Pole: 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”.

Focal Length: The distance between the pole and the principal focus of a spherical mirror is called focal length. Represented by f.

Magnification is the increase in the image size produced by spherical mirrors with respect to the object size. It is the ratio of the height of the image to the height of the object and is denoted as m. The magnification, m produced by a spherical mirror can be expressed as:

m=h/h′
