The second harmonic of a 380 kHz frequency is:

Explanation:
The second harmonic of a fundamental frequency is obtained by multiplying that frequency by two. In this case, the fundamental frequency is 380 kHz. To find the second harmonic, you calculate it as follows: Second harmonic = 2 × Fundamental frequency Second harmonic = 2 × 380 kHz = 760 kHz. This demonstrates that 760 kHz is indeed the correct answer as it represents the frequency at which the second harmonic occurs. Understanding harmonics is essential in radiocommunications because it helps to comprehend how signals can propagate and interact based on their frequency characteristics.
