The speed of sound in air, symbol v, is approximately constant at 340 metres per second. (You do not need to memorise this value.) As temperature increases, the speed increases slightly.

Speed, frequency and wavelength are related by the formula v = f Ã— Î». Other forms of this relationship are f = v/Î» and Î» = v/f. Because the speed is approximately constant, it follows that frequency and wavelength are inversely pr

I've found it's not at all uncommon to discover I have a stake in a situation. Complex situations often spread their tentacles into all sorts of areas, so that the number of people touched by them can be very large.
