# Tuning Fork (Sound/Frequency)

• whitehorsey
In summary, the frequency of the second tuning fork can be calculated by taking the absolute value of the difference between the frequencies of the two tuning forks. In this case, since the first tuning fork has a frequency of 440 Hz and the beats produced are 5.0 per second, the second tuning fork must have a frequency of either 435 Hz or 445 Hz, depending on which one is considered "slightly lower pitch".

1. A tuning fork has a frequency of 440 Hz. If another tuning fork of slightly lower pitch is sounded at the same time, 5.0 beats per second are produced. What is the frequency of the second tuning fork?

2. change of f = absolute value of f2 - f1

3. change of f = absolute value of f2 - f1
-5 = f2 -440 5 = f2 -440
435 Hz, 445 Hz ---- I got two answers but the question only asks for one (because i don't see a plural in frequency) which one is right and can you tell me why? Thank You! [/b]

Question says "of slightly lower pitch"...

oh thank you! :)

## 1. What is a tuning fork?

A tuning fork is a small metal instrument with two prongs that produces a specific pitch when struck against a surface. It is used to tune musical instruments and to test the accuracy of sound frequencies.

## 2. How does a tuning fork work?

When a tuning fork is struck, it vibrates at a specific frequency, producing a pure sound wave. This frequency is determined by the length and thickness of the prongs. The sound wave then travels through the air and reaches our ears, allowing us to hear the pitch.

## 3. What is the purpose of a tuning fork in science?

In science, tuning forks are used to measure and demonstrate sound frequency. They are also used in experiments to study the properties of sound waves and to calibrate instruments that measure sound.

## 4. How do you use a tuning fork to tune an instrument?

To tune an instrument with a tuning fork, strike the fork against a surface and hold it near the instrument. Adjust the instrument until the pitch of the tuning fork matches the desired note. This ensures that the instrument is in tune with the standard pitch of the tuning fork.

## 5. Can a tuning fork produce different pitches?

Yes, a tuning fork can produce different pitches depending on its size and shape. The longer and thicker the prongs, the lower the pitch will be. If the prongs are shorter and thinner, the pitch will be higher. However, the pitch will always be a pure tone, without any overtones or harmonics.
