Fundamental And Harmonics

In the section of the standing waves, there is some confusion over the fundamental and the harmonics with what I have written in the notes. Well,books are not uniform in naming the fundamental, harmonics or the overtones. To settle it once and for all, we will adopt the followings for standing waves :-

1 Loop

First Harmonic or Fundamental

2 l00ps

Second Harmonic or First Overtone

3 Loops

Third Harmonic or Second Overtone
