Answer 1

Sign convection..........

◆All the distance measured from pole.

◆Directiom of incident ray will be positive and opposite to it will negative.

◆Height of image above principal axis is positive and below it, it is negative.

Answer 2

The following sign convention is used for measuring various distances in the ray diagrams of spherical mirrors:

Object is always placed to the left of mirror
All distances are measured from the pole of the mirror.
Distances measured in the direction of the incident ray are positive and the distances measured in the direction opposite to that of the incident rays are negative.
Distances measured along y-axis above the principal axis are positive and that measured along y-axis below the principal axis are negative.

Sign Convention for Spherical Lenses

All the distances are measured from the optical center of the lens.
The distances measured in the same direction as that of incident light are taken as positive.
The distances measured against the direction of incident light are taken as negative.
The distances measured upward and perpendicular to the principle axis are taken as positive.
The distances measured downwards and perpendicular to principle axis is taken as negative.
