Which among iron cobalt nickel and manganese forms octahedral conolex?

Answer»

he LENS addition formula adds the RECIPROCAL of the COMPONENT focal lengths , the resulting focal length will be 1/2 the original focal length.Here’s the BREAK down: 1/f = 1/f1 + 1/f2. where f1 = f2.1/f = 1/f1 + 1/f1 = 2/f1, so f = f1/2.Similarly, if three lenses were PLACED in contact, then the combined focal length would be 1/3 of a single lensI hope this will help youIf not then comment me
