Waving
In physics a wave is a disturbance or oscillation that travels through spacetime, accompanied by a transfer of energy. Wave motion transfers energy from one point to another, often with no permanent displacement of the particles of the medium—that is, with little or no associated mass transport. They consist, instead, of oscillations or vibrations around almost fixed locations. Waves are described by a wave equation which sets out how the disturbance proceeds over time. The mathematical form of this equation varies depending on the type of wave.

Famous quotes containing the word waving:
“There can be no reconciliation where there is no open warfare. There must be a battle, a brave boisterous battle, with pennants waving and cannon roaring, before there can be peaceful treaties and enthusiastic shaking of hands.”
—Mary Elizabeth Braddon (1837–1915)
“But he her fears to cease
Sent down the meek-eyed Peace;
She, crowned with olive green, came softly sliding
Down through the turning sphere,
His ready harbinger,
With turtle wing the amorous clouds dividing,
And waving wide her myrtle wand,
She strikes a universal peace through sea and land.”
—John Milton (1608–1674)
“That would be waving and that would be crying,
Crying and shouting and meaning farewell,
Farewell in the eyes and farewell at the centre,
Just to stand still without moving a hand.”
—Wallace Stevens (1879–1955)
