Question

What is the cartesian sign convention used for spherical mirrors?

Answer 1

Since, object is always placed in front of themirror hence the sign of object is taken as negative. Since, the centre of curvature and focus lie in front of the concave mirror, sosigns of radius of curvature and focal length are taken as negative in the case of concave mirror.This sign convention is known as New Cartesian Sign Convention. Sign is taken as – (negative) from pole of a spherical mirror towards object along the principal axis. This means sign is always taken as – (negative) in front of a spherical mirror.

Answer 2

Answer:

Explanation:

The sign convention is known as new Cartesian sign convention. Sign is taken as - (negative) from pole of a spherical mirror towards object along the principal axis this means sing is always taken as - (negative) in front of a spherical mirror
