Webb4 apr. 2024 · Peak voltage, which we designate as VP, is measured from the horizontal axis (at 0 reference height) to the top of the waveform or crest. AC Peak Voltage vs. AC Peak-to-Peak Voltage. Keep in mind that AC stands for alternating current, and this also means that the voltage alternates (changes polarity) a set number of times in a given period. WebbThe speed of propagation vw is the distance the wave travels in a given time, which is one wavelength in a time of one period. In equation form, it is written as. v w = f λ. From this relationship, we see that in a medium where vw is constant, the higher the frequency, the smaller the wavelength. See Figure 13.8. diana ross childhood
