Potential energyPotential energy is usually defined using a field and a particle that experiences the field force, as the work down in moving a unit particle from infinity to a position in that field. But some physics text books describe the particle placed there as possessing potential energy,...
In this case the perturbing ions and electrons can be described in the same way, i.e., in terms of collisions. Additional effects occuring at low densities such as fine structure, Lamb shift and Doppler effects are also discussed. It is pointed out that a similar discussion may also be ...

Why do the electricity does not pass through a river however it consists water in it? Define current. What is meant when we say that Energy is transferred in solids by conduction? How will we define charge? What is meant by compressibility?
is where the oscillations in a wave are confined to one direction only in a plane normal to the direction of transfer of energy of the wave.OROscillations occur only in one plane, parallel to the direction of energy transfer.(b) (A polarised wave vibrates in a single plane in space.) ...
Nuclear energy results when the mass of atoms is converted to energy through nuclear reactions. This energy-mass conversion was explained by Albert Einstein in 1905. You can also understand the binding energy of a nucleus of an atom through this energy-mass conversion relation....
