Once there is any instability, a high pressure zone on one side of the flag moves the fabric, and the wind interacts with the fabric to translate the bumped out region in the downweb direction. Meanwhile the fabric interacts with the wind to increase the flow into the high pressure area and make the bumping out effect stronger. The displacement of the fabric travels toward the free end of the flag as a moving wave, and the free end flops back and forth, approximately following an arc around a point near the end of the flag. This travel in an arc creates a tension in the end of the flag (from the point of view of a coordinate system based on the flag, this would be centrifugal force). The coupling of wind energy into this traveling wave is what powers the fabric motion, much as it powers surf energy by coupling into ocean waves.
I'd consider this a problem from the field of mechanical engineering, more specifically an example of fluid-structure interaction (fsi). To model it effectively would require coupled models, one of them a computational fluid dynamics (CFD) model, and the other a mechanical model including the tension, mass, velocity, and possibly stiffness of the points in the flag. This is somewhat hard work.
Seems totally out of place in a chemistry exam, unless they want some sort of trick answer like solar energy driving the cycle of winds on Earth.
the wind speed,wind duration and the distance the wave is traveling
No, a flag cannot wave in space where there is no atmosphere to create wind.
A wave that increases in height due to strong winds is called a wind wave. Wind waves are generated by the transfer of wind energy to the water's surface, causing the water to form crests and troughs that increase in size as the wind speed or duration of wind increases.
Wind causes flags to flutter because it creates variations in air pressure around the flag. As the wind blows against the flag, it creates turbulence, which results in the flag moving back and forth. This movement is what causes the fluttering motion of the flag.
No, wave action is caused by wind. When wind blows over the surface of a body of water, it creates friction and transfers some of its energy into the water, forming waves. So, wind is the primary driver behind wave action.

There's no wind on the moon.
the wind speed,wind duration and the distance the wave is traveling
Well it depends. If its a big wave, there lots of wind. If its a small wave, there's probably little wind. It has to be strong enough. Surprisingly, waves comes from wind.

Yes your exactly right
The cause of waves depends on the strength of the wind. The stronger the wind the bigger the wave.
