Question

wavelength of light in vaccum ?

Answer 1

A dipole exists when two or more atoms with different electronegativities are bonded together to form a molecule. The resulting unequal sharing of electrons leads to a molecule with a net positive end and a net negative end.

Answer 2

theres a magnetic dipole and a electric dipole.... which are formed when opposite polarities are held together (due to attraction) at a finite distance..

Answer 3

thank u

Answer 4

Dipole-dipole interactions exist between molecules that are permanently polar. This requires the presence of polar bonds and a asymmetric molecule. These molecules have a permanent separation of positive and negative charge. In the illustration the H end of HCl is permanently slightly positive charge. The Cl end of HCl has a permanent slight negative charge. the "H" in one molecule is attracted to the "Cl" in a neighbor. The intermolecular force is weak compared to a covalent bond. But this dipole-dipole interaction is one of the stronger intermolecular attractions.
