Question

define pole of mirror, principal axis, focal length, center of curvature, aperture

Answer 1

heya friends !!?

here is ur answer
___;:::_____________
1)pole -the central point of spherical mirror is called pole .

2)principal axis-A line passes through the centre of curvature and pole of mirror.

◆it is denoted by "r"

3)focal length - it is the distance between pole and the centre of curvature

4)centre of curvature - it is the centre of that sphere of which of the mirror is a part.

5)Aperture -It is the length of the mirror from where reflection take place sometimes it is understood as the diameter of mirror.


hope it help you ☺

Answer 2

Pole = the centre point of reflecting surface of a spherical mirror is called POLE
Principal axis = the line joining pole P and centre of curvature C of the mirror and extended on either side is called PRINCIPAL AXIS of the mirror
Focal length = the distance between the pole P and principal focus F of a spherical mirror is called its FOCAL LENGTH
Centre of curvature = the centre of curvature of a spherical mirror is the centre of the hollow glass sphere, of which the given mirror is a part
Aperture = the diameter of a spherical mirror is called its APERTURE
