The fundamental frequency is 40 Hz ,thefrequency of 3rd overtobe is? nd how?

The frequency of the 3rd overtone can be calculated by multiplying the fundamental frequency by 3.

Therefore, the frequency of the 3rd overtone would be:

40 Hz * 3 = 120 Hz

So, the frequency of the 3rd overtone is 120 Hz.

Formula for Frequency of an Overtones:

Frequency of nth overtones (fn) = n - Fundamental Frequency (f)

Given:

- Fundamental Frequency (f) = 40 Hz
- We want to find the frequency of the 3rd overtone (f3)

Calculation:

f3 = 3 - f
f3 = 3 - 40 Hz
f3 = 120 Hz

Therefore, the frequency of the 3rd overtone (or harmonic) is 120 Hz.
