Tunning Fork  PYE Type

•   Size :- 20.3cm x 15.2 cm x 10.2 cm
•   Weight :- 767 gm 

A tuning fork is an acoustic resonator in the form of a two-pronged fork with the prongs (tines) formed from a U-shaped bar of elastic metal (usually steel). ... A tuning fork's pitch depends on the length and mass of the two prongs

SPECIFICATION

• Tuning fork Chromium plated use for producing sound waves by vibrating .
• The fork consists of a handle and two vibrating metal strip. When tuning fork hit with rubber hammer, the two vibrating metal strip begin to vibrate.
• The vibration of tuning folk produce disturbances of surrounding air molecules.
• Set of 8 tuning fork in chrome plated, each marked with its number with its number of vibrations. Superior quality.
• No of tunning forck in HZ  256 Hz C, 288 Hz D, 320 Hz E, 341.3 Hz, F, 384 Hz G, 426.6 Hz A, 480 Hz B and 512 Hz C. packed in Thermocol Box
• Pitches: the tuning forks are labeled C, D, E, F, G, A, B, C, representing the C Major scale. However, these tones are slightly flat of your standard C Major scale. So, if your intent is to use these as a reference pitch, such as to tune a guitar, these are not the forks for you.

HOW TUNNING FORK  WORK

By hitting a tuning fork, you're causing its tines to vibrate back and forth several hundred times per second. Often, the vibrations are so fast that they're not visible to the human eye. If you need proof, simply dip a humming tuning fork into a cup of water -- it'll kick up a surprisingly large jet of water. In scientific terms, the speed of a tuning fork's vibrations is known as its frequency, a quantity measured in hertz (Hz), or vibrations per second.

The faster a tuning fork's frequency, the higher the pitch of the note it plays. For instance, for a tuning fork to mimic the top key on a piano, it needs to vibrate at 4,000 Hz. To mimic the lowest key, on the other hand, it would only need to vibrate at 28 Hz.
