Answer 2

Hi friend_______,

Cartesian sign conventions are used for measuring the various distances in the ray diagrams of spherical lenses. According to Cartesian convention:

★ The object is always placed on the left side of the lens.

★ All the distances are measured from the optical centre 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 principal axis is taken as positive.

★ The distances measured downward and perpendicular to the principal axis is taken as negative.
