The frequency of tuning fork can be determined by sonometer. A Sonometer is a device that is used for demonstrating the relationship between the frequency of the sound wave produced by a plucked string, and the tension, length, and mass per unit length of the string.

Tuning Fork, a small U-shaped piece of steel that, when struck, produces a clear tone of unvarying pitch. A tuning fork is used for adjusting the tone of a musical instrument and finding a standard pitch, usually A above middle C. It is also used for studying sound in the physics laboratory.

Currently, the most common tuning fork sounds the note of A = 440 Hz, the standard concert pitch that many orchestras use.

Sonometer to find the frequency of a tuning fork

1. Explanation:
2. frequency * length = constant for both cases.
3. So f1 * L1 = constant = f2 * L2.

In clinical practice, the 512-Hz tuning fork has traditionally been preferred. At this frequency, it provides the best balance of time of tone decay and tactile vibration. Lower-frequency tuning forks like the 256-Hz tuning fork provide greater tactile vibration. In other words, they are better felt than heard.

A tuning fork is a mechanism used in laboratory research to generate sound. The waves from the tuning forks are transferred to the surrounding medium as the prongs of the tuning fork touch the surface of the water.

How it works:

Hint:When a tuning fork is loaded with wax, the frequency of the tuning fork decreases. Here, the beats produced per second remain the same before and after loading wax into the unknown tuning fork. The beats produced per second refers to the difference between the frequencies of the two tuning forks.

The main uncertainty is what epoch and continent the tuning fork is meant for. A is 440Hz in some places, 444Hz in others, many instruments are built for 442Hz, it has been 435Hz for most of 20th century and was something like 415Hz during the Renaissance. The proper way to determine that is to measure the fork with an electronic tuner. It will give you better than 0.5% precision.

The primary way that tuning forks produce sound is by placing the stem of the vibrating tuning fork on a resonating chamber. The stem of the fork is also vibrating.

Tuning forks emit pure sounds that are represented as pure sine waves, without any harmonics. Originally invented to create a pure tone to which musicians could tune their instruments, tuning forks have become, in last 4 decades, important tools in medicine and alternative therapies.

In modern quartz clocks, the quartz crystal resonator or oscillator is in the shape of a small tuning fork ( XY-cut ), laser -trimmed or precision lapped to vibrate at 32 768 Hz. This frequency is equal to 2 15 cycles per second.
