Any wave is identified by its wavelength (or frequency), and the wavelength is the distance between the two consecutive crests (or troughs) in wave trains. But wave is not identified by its amplitude. The wave could have been described by the amplitude as it doesn't require two wave trains (or...

In most of the books, the magnetic field is defied circularly without the physical concept. For example, it is defied like "a magnetic field is a vecor field that can be created by a moving electric field" Some books also defined by using mathematical formula. With this type of defination, it...

Difference between Enthalpy and Internal energy: When we add heat (energy) to a system the system’s energy will be increased. We say this energy is stored within the system. Similarly, when we remove some heat from the system, its energy will reduce. Do we know the total effect within...
