Answers
Refer to the concave mirror in the pic
Parts of concave mirror
Centre of curvature
the centre of curvature of a spherical mirror is the centre of the hollow sphere of glass of which the mirror is part
Pole
The centre of a spherical mirror is called its pole
The straight line passing through the centre of curvature and pole of a spherical mirror is called its principal axis
The portion of a mirror from which the reflection of light actually takes place is called the aperture of the mirror
the radius of curvature of a spherical mirror is the radius of hollow sphere of the class of which the mirror is part
The principal focus of a concave mirror is a point on its principle access to which all the light rays which are parallel and close to the excess converge after reflection from the concave mirror
The focal length of a concave mirror is the distance between its pole and principal focus
concave mirror:
1. pole : it is the mid point of the concave mirror. denoted with leter p
2. focal length : it is the distance between p and principal Focus . denoted with (f)
3. radius of curvature: it is the radius of the concave mirror.
4. cente of curvature : it is the centre of the imaginary sphere made by concave mirror.
