WebAccording to the new cartesian sign convention, pole of the mirror is taken as the origin. All the measurements of object distance, image distance and the focal length are recorded from the pole of mirror. All measurements are positive in the direction of incident rays whereas that and its opposite measurements are taken as negative. WebApr 6, 2024 · Verified. 191.4k + views. Hint: Sign conventions refers to the negative and the positive sign that we must use for the calculation of any variable equation.

WebThe sign convention for spherical mirrors has a set of rules to be followed that is known as the “New Cartesian Sign Convention" as described below: The pole(p) of the mirror acts as the origin. The principal axis acts as the x-axis of the coordinate system. The object is kept on the left of the mirror. This is to be followed in all situations. WebApr 4, 2024 · Cartesian sign convention in case of convex mirror: $1.$ Since, the object is always placed in front of the mirror hence object distance is taken as negative. $2.$ Since, the centre of curvature C and focus F lies behind the convex mirror, so radius of curvature and focal length are taken as positive in the case of convex mirror. WebWithout signs we have to explicitly mention we're dealing with a concave mirror, or a convex mirror, or the images in front of the mirror, or the images behind the mirror. But with Signs these things are done mathematically. For example, if I just say negative focal length it … ponta delgada where to stay
