Question

In chapter light
give definition for

• p ( poles )
•R ( radius of curvature )
• C ( center of curvature )
• principal axis
• F ( principal focus )
• f ( focal length ) ​

Answer 1

Answer:

pole : The centre of the reflecting surface of a spherical mirror

Explanation:

R : For a curve, it equals the radius of the circular arc which best approximates the curve at that point.

C : distance from the curve equal to the radius of curvature

principal axis : line that passes through the center of curvature

F : the point where light rays originating from a point on the object converge

f : measure of how strongly the system converges or diverges light
