What is the first harmonic frequency of a radio wave with a fundamental frequency of 2,000 kHz?

The first harmonic frequency of a radio wave is defined as its fundamental frequency. In this case, the fundamental frequency specified is 2,000 kHz. Harmonics are integral multiples of the fundamental frequency, but the first harmonic, also known as the fundamental itself, will be the same as this frequency.

Therefore, when identifying the first harmonic frequency, it is simply the frequency of the wave itself, which is 2,000 kHz. The subsequent harmonics would be multiples of this frequency: the second harmonic would be at 4,000 kHz (2 times the fundamental), and the third harmonic would be at 6,000 kHz (3 times the fundamental), and so on. This concept of harmonics is crucial for understanding wave behavior in various contexts, especially in electronic communication systems.
