Answer :
The fundamental frequency of the A4 violin is 440 Hz.
What is fundamental frequency?
The fundamental frequency of a vibrating string depends on several factors including its length, tension, and mass per unit length. Violin strings typically have a range of fundamental frequencies depending on their thickness and the pitch they are tuned to.
For instance, the standard tuning for a violin is G3, D4, A4, and E5, where the numbers indicate the octave and the letters denote the pitch class.
The fundamental frequency for each string in standard tuning is:
G string (G3): 196 Hz
D string (D4): 293.66 Hz
A string (A4): 440 Hz
E string (E5): 659.25 Hz
Since the violin is A4, we conclude that the fundamental frequency is 440 Hz.
The complete question is below:
The fundamental frequency is the lowest frequency that a string can vibrate at. If our violin is A4, what is the fundamental frequency for our violin in Hz?
