you're looking at a rocket exhaust plume at high altitude being illuminated by the sun from beyond the horizon
it looks wavy because the wind at different altitudes and locations along the path has blown the trail in different directions
toward the end of the trail the plume starts to look more wispy due to the lower atmospheric pressure at high altitude

this is known as the "twilight phenomenon" or the "jellyfish effect"
