Q6 of 13 Page 127

Three mirrors are created from a single sphere. Which of the following - pole, center of curvature, radius of curvature, principal axis - will be common to them and which will not be common?

1.) Radius of Curvature = It will be common because the radius of the sphere of which the mirror is a part will be same for every part of the mirror.

2.) Principal Axis = It will not be common.


3.) Pole = It will not be common.


4.) Center of curvature = It will be common because the center of the sphere of which the mirror is a part will be same for every part of the mirror.
