Question

what do you know about the terms given below related to spherical mirrors? a) pole b) centre of curvature c) focus d)radius of curvature e)focal length. f) principal axis. g) object distance. h) image distance. i) magnification​

Answer 1

Answer:

Pole: It is the center of the reflecting surface of the concave mirror

The centre of curvature is the centre of the sphere from which the mirror is cut

Focus is a point onto which collimated light parallel to the axis is focused.

Radius of curvature:

The plane mirror is a part of sphere with infinite radius . It's every part is a part of sphere. Hence, its radius of curvature is infinite.

Focal length : when the parallel rays of light strike the mirror they get reflected back parallel to each other.

The principal axis is called a line that passes via the centre of the surface of a spherical mirror or lens and through the centre of curvature of all segments of the mirror or lens.

The distance between the object and the pole of the mirror is called the object distance(u).

The distance between the image and the pole of the mirror is called Image distance.

Magnification is a measure of the size of an image compared to the size of the object.
