Traveling and Standing Waves
Since sine waves propagate without changing form in distributed linear systems, they are often used to analyze wave propagation. Sine waves traveling in two directions can be represented as
- and .
When two waves having the same amplitude and frequency, and traveling in opposite directions, superpose each other, then a standing wave pattern is created.

Famous quotes containing the words traveling, standing and/or waves:
“It is impossible for a stranger traveling through the United States to tell from the appearance of the people or the country whether he is in Toledo, Ohio, or Portland, Oregon. Ninety million Americans cut their hair in the same way, eat each morning exactly the same breakfast, tie up the small girls’ curls with precisely the same kind of ribbon fashioned into bows exactly alike; and in every way all try to look and act as much like all the others as they can.”
—Alfred Harmsworth, Lord Northcliffe (1865–1922)
“I ask a wreathwhich will not crush my head.
And there is no hurry about it;
I shall have, doubtless, a boom after my funeral,
Seeing that long standing increases all things
regardless of quality.”
—Ezra Pound (1885–1972)
“Dr. Scofield’s equipment, which you have just seen, radiated waves direct to Professor Houghland’s laboratory. When these waves came in contact with those the professor’s equipment was radiating, they created the interstellar frequency, which is the death ray.”
—Joseph O’Donnell, and Clifford Sanforth. Arthur Perry (Bela Lugosi)
