Posted By: SteamyTeaHave you brushed up on your Laws of Indices, BIDMAS/BODMAS and rearranging equations?

Posted By: fostertomSo velocity of propagation ... depends also on frequency of the oscillation
Posted By: fostertomWhat would a step change in amplitude of input count as?
Posted By: djhPosted By: fostertomWhat would a step change in amplitude of input count as?Ah, now you start getting into more complicated territory. It's usually modelled as a series of waves of ever-increasing frequency, superimposed on one another. If you limit the high frequencies, you round off the corners of the step. So, many wavelengths, some of them infinitely small.
Posted By: fostertomIt seems to me that vSHC divided by Conductivity should give a result of time per 1cm lamina (s/cm). Or inversely, speed of propagation (cm/s - or m/s).But apparently it doesn't - it gives m2/s.
