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 wave:
“We are caught up Mr. Perry on a great wave whether we will or no, a great wave of expansion and progress. All these mechanical inventionstelephones, electricity, steel bridges, horseless vehiclesthey are all leading somewhere. Its up to us to be on the inside in the forefront of progress.”
—John Dos Passos (18961970)
“Through this broad street, restless ever,
Ebbs and flows a human tide,
Wave on wave a living river;
Wealth and fashion side by side;
Toiler, idler, slave and master, in the same quick current glide.”
—John Greenleaf Whittier (18071892)
“Justice was done, and the President of the Immortals, in Æschylean phrase, had ended his sport with Tess. And the dUrberville knights and dames slept on in their tombs unknowing. The two speechless gazers bent themselves down to the earth, as if in prayer, and remained thus a long time, absolutely motionless: the flag continued to wave silently. As soon as they had strength they arose, joined hands again, and went on.
—Thomas Hardy (18401928)
