Famous quotes containing the words frequency, sound and/or waves:

“There have been many stories told about the bottom, or rather no bottom, of this pond, which certainly had no foundation for themselves. It is remarkable how long men will believe in the bottomlessness of a pond without taking the trouble to sound it.”
—Henry David Thoreau (1817–1862)

“O beautiful for spacious skies,
For amber waves of grain,
For purple mountain majesties
Above the fruited plain!”
