Q1
The frequency of a wave is 10 Hz. What is the frequency of its second harmonic? (2021)
5 Hz
10 Hz
20 Hz
30 Hz
The frequency of the second harmonic is twice the fundamental frequency. Therefore, if the fundamental frequency is 10 Hz, the second harmonic frequency is 2 * 10 Hz = 20 Hz.

Q
Q: The frequency of a wave is 10 Hz. What is the frequency of its second harmonic? (2021)
Solution: The frequency of the second harmonic is twice the fundamental frequency. Therefore, if the fundamental frequency is 10 Hz, the second harmonic frequency is 2 * 10 Hz = 20 Hz.
Steps: 5
Step 1: Understand that the fundamental frequency is the first harmonic of the wave. In this case, it is given as 10 Hz.
Step 2: Know that the second harmonic is the frequency that is twice the fundamental frequency.
Step 3: Calculate the second harmonic by multiplying the fundamental frequency (10 Hz) by 2.
Step 4: Perform the calculation: 2 * 10 Hz = 20 Hz.
Step 5: Conclude that the frequency of the second harmonic is 20 Hz.
