... Electromagnetic radiation is a form of energy transition in which electric and magnetic fields are propagated as waves through empty space (a vacuum) or through a medium such as glass. An electric field is the region around as electrically charged particle. A magnetic field is found in the region su ...

... For each eigenvalue of L2, there are (2l+1) eigenfunctions of L2 with the same value of l, but different values of m. Therefore, the degeneracy is (2l+1). The Spherical Harmonic functions are important in the central force problem--in which a particle moves under a force which is due to a potential ...

WORK ENERGY THEOREM
... According to the work-energy theorem, the net work on an object causes a change in the kinetic energy of the object. The formula for net work is net work = change in kinetic energy = final kinetic energy - initial kinetic energy. The work W done by the net force on a particle equals the change in th ...
