Standing waves are formed when the reflected wave reinforces the initial wave at a resonant frequency. At other frequencies, the reflected wave tends to cancel out the initial wave. One example of a standing wave is when a guitar string is plucked. Due to the tension of the string, the length, and the mass, the string will vibrate at one frequency.
The speed of the wave is zero or near zero
Resonant conditions caused by reflection from opposing parallel surfaces or an improperly terminated loads
interference between the incoming and reflected waves of the same frequency
If a reflected wave and an incoming wave have just the right frequency, they produce a combined wave. This combined wave appears to be standing still.
The length of the tube and the wavelength of the given wave must match up accordingly so that there is an anti-node at the open end and a node at the closed end.
a standing wave rusults from?
resonance
I think so.
The progressive wave has to meet its own reflected wave. So both have same amplitude, wavelength. Hence standing waves become possible.
No. Otherwise it is no standing wave.

a standing wave.
A standing wave requires a relative motion of the medium at the same velocity of the wave

By examining a standing wave you can observe the frequency, wavelength, wave speed, and amplitude of the wave.
If the wave requires a medium then it is a mechanical wave.

a standing wave.
When an incoming wave combines with a reflected wave in such a way that the combined wave appears to be standing still the result is a standing still wave.
standing wave!
