Web30 de mai. de 2013 · Physicists rethink celebrated Kelvin wake pattern for ships. 30 May 2013. Accurate angles. Lord Kelvin may have been an accomplished sailor, but he might have missed a trick when he famously described the phenomenon of wakes fanning out at a constant angle of 19.47°, no matter the speed of the vessel. That is the claim of … WebToday, sound spectra (the plural of spectrum is spectra) are usually measured using. a microphone which measures the sound pressure over a certain time interval, an analogue-digital converter which converts this to a series of numbers (representing the microphone voltage) as a function of time, and. a computer which performs a calculation upon ...
