phase diference=path difference x (360 degrees/wavelength)
Relation between phase difference and path difference is path difference/wavelength=phase difference/2*pi
Because the path difference or the phase difference between two waves is zero
Only if you are grounded and provide a return path for the current to travel.
it is a path in which magnitude and phase can be determine . it is used to determine the
optical path = μ x geometricalpath
difference between shortest path and alternate path
only when under sail alone and is crossing path of powerboat
only when under sail alone and crossing the path of the powerboat
The path difference is the difference in the physical distance between the two sources to the observer, i.e., the difference in distance travelled from the source to the observer.
Neutral is a return path.
velosity in circular path angular
Earthing point is where conductor is directly connected to ground and its potential is always zero. Neutral is a return path in single phase system and in three phase system Neutral point will have zero potential if all the loads are balanced in the system. In un balanced three phase system even neutral point will have some potential
