See take these two cases. You have taken this one – some value say omega 1 equal to say 1 unit and some next one is 1.2 units; next is 1.4 units, like that. What it means? I have broken it all like that. Now, there can be wave, which is at 1.1 also in between. But, when I do that, what I did, I say that all the waves… Let me take this one. All the waves with the frequency between 1.1 to 1.3 – this much; energy of all the waves is equal to half of this A square, because I have only one wave; I broke it down.
