The following three waves have different periods. To rank each wave by period from shortest to longest, look at he distance between each peak. ... With sinusoidal functions, frequency is the number of cycles that occur in (2 pi). A shorter period means more cycles can fit in (2 pi) and thus a higher frequency. Period and frequency are ...

This relationship was also derived using a sinusoidal wave, but it successfully describes any wave or pulse that has the form y (x, t) = f (x ∓ v t). y (x, t) = f (x ∓ v t). These waves result due to a linear restoring force of the medium—thus, the name linear wave equation. Any wave function that satisfies this equation is a linear wave ...

Sine waves produce a very 'smooth' welding arc, but it is sometimes beneficial to alter this basic waveform. Square waves were the first alternative for the sine wave. The area inside the graph of the waveform represents the amount of heat put into the metal. It's easy to see that a square wave transfers considerably more heat than a sine ...
