frequency = speed of light/wavelength
Speed = frequency x wavelength.
Well, ask yourself what frequency is, not even necessarily in a mathematical sense. The frequency that something occurs is how often is happens. In a mathematical sense, frequency is just that, in terms of seconds. So the frequency in this case is 5.1/39.9s or roughly 0.128
In mathematical terms a weighted average is one which takes account of the popularity or frequency that particular numbers appear in the collection that is being averaged. It is considered to give a more realistic average.
