What Is the Beat Frequency Between Two Close Tuning Fork Frequencies?

In summary, when two tuning forks with frequencies of 256 Hz and 258 Hz are struck, the underlying "hum" frequency that is heard is 2 Hz. This is determined through the generation of beat frequencies from the sum and difference of the fundamental frequencies. However, it should be noted that while 2 Hz is the correct answer, it is not audible to the human ear.

Homework Statement



Two tuning forks are struck and the sounds from each reach your ears at the same time. One sound has a frequency of 256 Hz, and the second sound has a frequency of 258 Hz. The underlying "hum" frequency that you hear is:
A. 2 Hz
B. 256 Hz
C. 258 Hz
D. 257 Hz

Homework Equations


The Attempt at a Solution



I got it as 2 HZ

Probably. Computer generated question?

The hesitation is because no one can hear 2 Hz.
 
  • #3
Nah homework question!
 
  • #4
Is it 2HZ?
 
  • #5
yes, but I agree with Delphi--two hz is not audible. Beat frequencies are generated by sums and differences of the fundamentals. The only choice which makes sense is 2.
 

FAQ: What Is the Beat Frequency Between Two Close Tuning Fork Frequencies?

What does the frequency of a tuning fork mean?

The frequency of a tuning fork refers to the number of vibrations or cycles per second that the fork produces when struck.

Why is the frequency of a tuning fork important?

The frequency of a tuning fork is important because it determines the pitch or note that the fork will produce. Different frequencies correspond to different musical notes.

How is the frequency of a tuning fork measured?

The frequency of a tuning fork can be measured using a tool called a frequency meter or by counting the number of vibrations in a set amount of time.

Can the frequency of a tuning fork be changed?

Yes, the frequency of a tuning fork can be changed by altering its physical properties, such as its length or mass. This can be done by filing or adding weight to the fork.

What factors affect the frequency of a tuning fork?

The frequency of a tuning fork is affected by its length, mass, and material. It can also be affected by external factors such as temperature and humidity.
