If a tuning fork vibrates over an open pipe what causes vibrations in the air in the pipe?
Resonance
What else can I help you with?
Which part of the tuning fork vibrates?
The tines.
What is the relationship between the number on the tuning fork and the pitch of the tuning fork?
In a simplistic way, pitches are nothing more than vibrations in the air. These vibrations happen at certain frequencies (the number of vibrations per second, measured in Hertz). The more vibrations per second the higher we perceive that pitch to be. A440 is now the tuning standard - that means that that A, in the middle of the treble staff, vibrates 440 times per second, or at 440 Hz. A note an octave higher would vibrate at 880 Hz and an octave lower vibrates at 220 Hz. Most tuning forks are pitched at A440, but you can get other notes (and even other temperaments). Those other notes vibrate at different frequencies, so the number on the tuning fork correspond to the numbers of vibrations-per-second that tuning fork makes.
What happens when a tuning fork that is still vibrating touches a wooden desk?
the vibrations made by the tuning fork cause the paper to preduce a humming sound.
If one tuning fork vibrates at 340 Hz and a second one vibrates at 640 Hz which fork sends out a longer wavelength?
Lower frequency equates to a longer wavelength, so the 340 Hz tuning fork would emit a longer wavelength sound.
Why can tuning fork sounds be made louder by standing them on an empty wooden box?
a wooden surface is better for a tuning fork rather than, say, a metal surface because the wood vibrates less than metal, and doesn't interfere with the vibrations of the fork. rubber is probably the best surface to hit a fork on.
What kind of wave does a tuning fork create when it vibrates?
A tuning fork creates a sound wave when it vibrates.
Which part of the tuning fork vibrates?
The tines.
When a tuning fork vibrates over an open pipe and the air in the pipe starts to vibrate the vibration the tube are caused by?
The vibrations are caused by resonance.beatsresonanceThe vibrations that are set up in the second fork are called sympathetic vibrations, and the two forks are said to be in resonance.

What device makes vibrations?
A tuning fork .
What type of waves are produced by a tuning fork vibrating in air?
The tuning fork produces sound waves when it vibrates in air.
What are free vibrations?
A tuning fork struck result in free vibrations.
When a turning fork vibrates over an open pipe and the air in the pipe starts to vibrate the vibrations in the tube are caused by resonance?
Resonance occurs when the natural frequency of an object matches the frequency of external vibrations, causing it to vibrate at maximum amplitude. In this case, when the tuning fork vibrates over the open pipe, the air inside the pipe starts to vibrate at a frequency that matches the natural frequency of the pipe, leading to resonance and amplifying the sound produced.
How are amplitude of vibrations generated?
by the cycle of a tuning fork.
How waves are created and propagate when a tuning fork is struck?
Because of the tuning fork's vibrations. It creates compressional sound waves.
How are sound waves generated in air by a tuning fork?
When a tuning fork is struck, it vibrates and creates compressions and rarefactions in the air, which travel as sound waves.
How can you prove the mechanical nature of sound by a simple experiment?
One simple experiment to prove the mechanical nature of sound is by using a tuning fork. When a tuning fork is struck and held against a table, the vibrations produced can be felt as the table vibrates. This demonstrates how sound is a result of mechanical vibrations traveling through a medium, in this case air, to reach our ears.
