Question

how centre of curvature is placed on zero dgree of a concave mirror?​

Answer 1

hiiiiiiii...

here is the answer....

This happens because the ray is coming from the center of the sphere of which this curved mirror is the part and in case of circle normal at a point always passes through the centre of the circle. Since the angle of incidence is 0 the angle of reflection is also 0 degree and this ray retraces its path

sphere
