Final answer:
The fundamental frequency of the string is 41 Hz.
Step-by-step explanation:
To find the fundamental frequency of the string, we can use the formula: f₁ = (f₂ - f₁) / 2. Given that the two successive harmonics are 328 Hz and 410 Hz, we can substitute the values into the formula: f₁ = (410 Hz - 328 Hz) / 2 = 41 Hz. Therefore, the fundamental frequency of the string is 41 Hz.
