Q

The second harmonic of a 380 kHz frequency is:

🔍 Key Concepts

• Harmonics in radio frequencies (multiples of a fundamental frequency) • How to calculate the second harmonic of a given frequency • Basic multiplication of kilohertz (kHz) values

💭 Think About

• What does "second harmonic" mean in terms of how many times the original (fundamental) frequency? • If the fundamental frequency is 380 kHz, what simple arithmetic operation would give you the second harmonic? • After you find the numerical value, which answer choice has that same value and correct unit (kHz)?

✅ Before You Answer

• Be sure you are multiplying, not dividing, to find the second harmonic • Confirm that you keep the units in kHz when you do the calculation • Eliminate any choices that are not in kHz or are not a simple multiple of 380 kHz
