write the new cartesian sign convention for reflection by spherical mirrors
Answers
Explanation:
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.
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.
