explain the cartision sign convention for spherical mirror?
Answers
1)All the distances in a ray diagram of reflection by spherical mirrors are measured from the pole of the spherical mirror.
2)The distances measured in the direction of incident light are taken as positive.
3)The distances measured in the direction opposite to the direction of incident light are taken as negative.
4)The heights measured upwards and perpendiculars to the principal axis of the mirror are taken as positive.
5)The heights measured downwards and perpendiculars to the principal axis of the mirror are taken as negative.
Heya mate...!!

Sign Convention for Spherical Mirror: Cartesian Sign Convention: In the case of spherical mirror all signs are taken from Pole of the spherical mirror, which is often called origin or origin point. ... Sign is taken as – (negative) from pole of a spherical mirror towards object along the principal axis.
