rude man said:I didn't see any discontinuity. Maybe the OP corrected the image?
EDIT: NM I see your point. The wording is horrible. The problem is not fully stated no matter how you rearrange the given data. The tuning fork frequency is obviously needed. The 3 Hz is a beat, not the tuning fork frequency. Etc.
somecelxis said:why The 3 Hz is a beat, not the tuning fork frequency?
rude man said:Well, for one thing you couldn't hear a 3 Hz tuning fork.
For another, the problem is horribly badly described so I made a guess that the 3 Hz is intended to be a beat frequency and the tuning fork frequency was omitted.

The frequency of a string or tuning fork refers to the number of vibrations or cycles that occur per second. It is measured in Hertz (Hz) and is directly related to the pitch of the sound produced. The higher the frequency, the higher the pitch.
The frequency of a string or tuning fork is determined by several factors, including the length, tension, and mass of the string or tuning fork. The longer the string or the higher the tension, the higher the frequency will be. The mass of the string or tuning fork also affects the frequency, with heavier objects producing lower frequencies.
The frequency of a string or tuning fork directly affects the pitch of the sound produced. The higher the frequency, the higher the pitch and vice versa. Additionally, the harmonics or overtones produced by the string or tuning fork are also affected by the frequency, creating a more complex and rich sound.
Yes, the frequency of a string or tuning fork can be changed by altering its length, tension, or mass. This can be done by adjusting the length of the string, tightening or loosening the tension, or adding or removing weight from the tuning fork.
The frequency of a string or tuning fork is important in music because it determines the pitch of the sound produced. By changing the frequency, different notes and melodies can be created, allowing for a wide range of musical expression. Additionally, the precise tuning of instruments, such as guitars and pianos, relies on the accurate measurement and adjustment of their frequencies.
