Important Consequences of the New Cartesian Sign Convention followed for Reflection of light by Spherical Mirrors
Consequences of new Cartesian sign convention:In new Cartesian sign convention, the poll P of the spherical mirror is taken as the origin and the principal axis of the mirror along the X-axis of the coordinate system. Keeping this in mind, we can easily note the following facts: (i) Object distance u is always taken negative, because the object is placed on the left of the mirror. ADVERTISEMENTS: (ii) In case of a concave mirror, a real image is formed in front (left) of the mirror and a virtual image is formed behind (right of) the mirror, so image distance v is negative for a real image and positive for a virtual image.(iii) In case of a convex mirror, the image distance v is always positive because the image is formed…
