Answers
Answer:
(a) Centre of curvature: center of the hollow sphere of glass of which the mirror is a part.
(b) Radius of curvature: radius of the hollow sphere of glass of which the mirror is a part.
(c) Pole: The centre of a spherical mirror is called its pole.
(d) Principal axis: The straight line passing through the centre of curvature and pole of a spherical mirror is called its principal axis.
(e) Aperture: The portion of a mirror from which the reflection of light actually takes place is called the aperture of the mirror.
Answer:
HERE IS UR ANSWER!!
Explanation:
(a) 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 a part.
(b) Radius of curvature:
The radius of curvature of a spherical mirror is the radius of the hollow sphere of glass of which the mirror is a part.
(c) Pole:
The centre of a sperical mirror is called its pole.
(d) Principle axis:
The straight line passing through the centre of curvature and pole of a spherical mirror is called its principal axis.
(e) Aperture:
That person of a mirror from which the reflection of light actually takes place is called the aperture of the mirror.
