Howdy! can be replied to with just a nod and a smile. It simply means Hi! in Texan - not How are you doing?. Or you might reply, Hey Y'all Doon? if you want to engage in proper Texan interactions. Replying in proper English, well pronounced, with each syllable clearly spoken, is HIGHLY discouraged.
The crest of a wave is the point of maximum positive displacement, or upward movement, away from equilibrium, or an undisturbed state. The opposite of crest is trough, which is the point of the greatest negative, downward displacement.
Aside from water and energy, the two main parts of a wave are its CREST, the area that is farthest from the Earth's core, and its TROUGH, the part of the wave that forms just â¦ before it gives way to the next crest. When two or more waves combine, their energies are combined.
