if I see this spectrum, suppose I take a signal; it will look something like that typically. Now, you see omega is reverse of T; and, that means, this side is omega, this side is T; that means, this side is also lambda in proportion, because remember, higher frequency means lower period means lower wavelength. So, in a sense, it is like that. Most of the signals that has been analyzed turns out… When people do that, is having a shape like that. Once again, it is a non-Gaussian, but Rayleigh shape. Same as what we discussed earlier. Obviously, what people have done, oceanographers – they went around the oceans for ages, for 100 years in their oceanographic ships; people have kept on measuring these signals and analyze that. So, you would have done it. You will end up finding some spectrum; it will probably look something like that. Energy – it will
