Amplitude of a stationary wave

[Josielle Abdilla]

Does each point in a stationary wave change its displacement and hence it's amplitude? If yes, why is this so? However, why does the amplitude at the node and antinode remains zero and maximum respectively? Does the above have to do with the fact that all the formation of a stationary wave is momentarily? What other dissimilarities stand between a progressive and a stationary wave?
Thanks :})

Each point on a stationary wave has a fixed amplitude that is different from the point next to it. Nodes have zero amplitude, antinodes have the largest amplitude than any other point.

What about in a progressive wave, do all particles have same amplitude?

However, the wave moves as the progressive waves continue to interfere, hence why shouldn't the amplitude change?
