pitch and intensity than thefundamentals. If these overtones are even multiples of the funda-mentals they are called harmonics. As Ohms law states, these harmonics are heard by the ear asseparate simple tones. If the wave be photographed by any means,we find net the separate harmonics at various… … In the above figure is shewn a wave (a) which is the resultantof the two waves, (b) and (c) having the frequency n and 2n. Sowin photographing waves by the method described in the next chapter(a) is the one obtained. To study the quality the wave must bebroken down or -analyzed into the sum of…
