What are single ends? The extreme fiber optics conductor is farthest from the illuminator. The bit which emits light or the end that lights up.
Define isothermal process For isothermal process temperature remains constant i.e. Δu = 0. Thus according to first law of thermodynamics ΔQ =Δw Heat supplied to the syste
Natural and forced vibrations When we strike a tuning fork with a rubber hammer it vibrates with certain frequency. The frequency does not change even if we hit it harder.
The higher power level band is called as the conduction band. (i) It is also called as empty band of minimum energy. (ii) This band is partially filled by the electrons. (
