If the fundamental frequency is 200 megahertz, what is the third harmonic?

To determine the third harmonic of a fundamental frequency, you multiply the fundamental frequency by the harmonic number. In this case, the fundamental frequency is 200 megahertz, and the third harmonic is found by multiplying that frequency by 3.

Calculating it:

Third harmonic = Fundamental frequency × Harmonic number

Third harmonic = 200 megahertz × 3 = 600 megahertz.

Thus, the third harmonic of a fundamental frequency of 200 megahertz is indeed 600 megahertz, making this choice correct. Understanding harmonics is crucial in various electronic applications, including signal processing and audio systems, as they illustrate how frequencies relate to and multiply from a base frequency.
