Waterfall A waterfall is usually a geology geologic formation resulting from water, often in the form of a stream, flowing over an erosion-resistant rock formation that forms a sudden break in elevation. Waterfalls may also be artificial, and they are sometimes created as garden and landscape ornament.
	Waterford Waterford (Irish language: Port Lirge) is, historically, the capital of County Waterford in Ireland, though today the city is administered separately from the county, the latter having its seat in Dungarvan. Local governance functions are handled by Waterford City Council.
	Watergate scandal The term "Watergate" refers to a series of events, spanning from 1972 to 1975, that got its name from burglaries of the headquarters of the Democratic National Committee in the Watergate Hotel complex in Washington, D.C.. Though then-President of the United States Richard Nixon had endured two years of mounting political embarrassments, the court-ordered release of the "smoking gun tape" about the burglaries in August 1974 brought with it the prospect of certain impeachment for Nixo
	Watering can A watering can is a portable container, usually with a handle and a spout, used to water plants by hand. It has existed since at least the seventeenth century and has since been improved.
	Waterline Waterline refers to an imaginary line marking the level to which ship or boat submerges in the water. To an observer on the ship the water appears to rise or fall against the Hull of the ship. Many factors determine the waterline. A heavy ship, or one heavily laden with cargo will submerge deeper in the water.
	Watermark A watermark is a recognizable image or pattern in paper that appears lighter when viewed by transmitted light . A watermark is made by impressing a water-coated metal stamp or dandy roll onto the paper during manufacturing. Watermarks were first introduced in Bologna, Italy in 1282; they have been used by papermakers to identify their product, and also on postage stamps, currency, and other government documents to discourage counterfeiting.

	Waveform Waveform means the shape and form of a signal , such as a wave moving across the surface of water, or the vibration of a plucked string. In many cases the medium in which the wave is being propagated does not permit a direct visual image of the form. In these cases, the term 'waveform' refers to the shape of a graph of the varying quantity against time or distance.
	Wavelength The wavelength is the distance between repeating units of a wave pattern. It is commonly designated by the Greek language letter lambda . In a sine wave, the wavelength is the distance between the midpoints of the wave: The x axis represents distance, and I would be some varying quantity at a given point in time as a function of x, for instance sound pressure or strength of the electric field or magnetic field for light.
	Wavelet In mathematics, wavelets, wavelet analysis, and the wavelet transform refers to the representation of a signal in terms of a finite length or fast decaying oscillating waveform . This waveform is Scaling and Translation to match the input signal. In formal terms, this representation is a wavelet series, which is the coordinate representation of a square integrable function with respect to a complete, orthonormal set of basis functions for the Hilbert space
