( ) Whenever any object in nature is tilted at an angle.....or in other times your angle of viewing the object gets tilted,....it's view/influence/ impact gets divided into two (or More) components.
FIRST COMPONENT AKA PARALLEL COMPONENT AKA REAL PART.THE PARALLEL COMPONENT . This component is the component which is parallel to wherever you are standing.
Mathematically put ....your frame of reference
( ) But in general, parallel to the some reference surface.
( ) Maybe it's called as the REAL PART because that's what you REALLY ACTUALLY get to see.
SECOND COMPONENT/PERPENDICULAR COMPONENT / REAL PART
( ) This is that component which is perpendicular to your frame of reference.
( ) So,... many a times you don't actually get to see it...you know.
( ) Maybe that's why they call it the imaginary part.
( ) For example, if you are standing along the wall which has the orange colored rectangle,...you won't be able to see the cylindrical portion of that tin.
( ) So, one can only guess work or imagine on what would be on the other relatively perpendicular side of the tin. So...the imaginary part.
ANALOGY/EXAMPLE NO 2
( ) For example let's take the example of this rod and the shadow caused by it.
( ) So, the shadow parallel to the ground (the one which is falling on the ground itself) is the real part as they say it.
( ) On the other hand,...the shadow falling upon the wall is the imaginary part.

Every equation now had as if something to say. A burning urge to share these things with the world aflamed within me. So that no one has to give up the subject that he or she loves the most.
