Question

what are carterian sign conventional used in spherical mirror ? what is the mirror formula​

Answer 1

Explanation:

the sign conventional in spherical mirror are

1 the object must be kept always in the left of the mirror

2 all distances parallel to the principal axis are measured from the pole of the mirror

3 all distances measured to the right of the origin are taken as positive while the lift of the origin are taken as negative

4 distances measured perpendicular to and above the pricipal axis are taken as positive

5 distances measured perpendicular to and below the principal axis are measured as negative

the mirror formula is 1/v+1/u=1/f
