Stationary (Standing) Waves : 

In physics, a standing wave, also known as a stationary wave, is a wave which oscillates in time but whose peak amplitude profile does not move in space. The peak amplitude of the wave oscillations at any point in space is constant with time, and the oscillations at different points throughout the wave are in phase. The locations at which the absolute value of the amplitude is minimum are called nodes, and the locations where the absolute value of the amplitude is maximum are called antinodes.

superposition of waves and superposition principle :-

When two or more waves arrive simultaneously in certain region of a medium, the particles of the medium are subjected to two or more simultaneous displacements, one due to each wave. The resultant displacement is the vector sum of full the displacements (because ( displacement is a vector) and a new wave motion is produced.
(a) Superposition of waves. The phenomena of intermixing of two or more waves to produce a new wave, is called superposition of waves.
(b) Superposition principle. The superposition principle states that the resultant displacement of a particle is equal to the vector sum of the individual displacements given to it by the superposing waves.

Fundamental, harmonics and overtones :-

When a body is vibrated, it vibrates with more than one frequencies. All the frequencies are an integral multiple of some least frequency.
The least frequency is called first harmonic or fundamental. Frequency double than the fundamental is called second harmonic, triple the fundamental is called third harmonic and so on. In general, a frequency n times the fundamental is called nth harmonic.
All frequencies, other than the fundamental are called overtones. They are called first, second, third overtones in order of their increasing frequency after the fundamental. Thus second harmonic becomes first overtone and third harmonic becomes second overtone. In absence of second harmonic, third harmonic becomes first overtone.
