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)
“Perfect present has no existence in our consciousness. As I said years ago in Erewhon, it lives but upon the sufferance of past and future. We are like men standing on a narrow footbridge over a railway. We can watch the future hurrying like an express train towards us, and then hurrying into the past, but in the narrow strip of present we cannot see it. Strange that that which is the most essential to our consciousness should be exactly that of which we are least definitely conscious.”
—Samuel Butler (1835–1902)
“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)
