Resonance
The vibrations are caused by resonance.

The vibrations that are set up in the second fork are called sympathetic vibrations, and the two forks are said to be in resonance.
The vibrations are caused by resonance, as they are carried by the air to the molecules in the interior of the pipe.
The vibrations of the tuning fork start the molecules of air to vibrate as well, sending them crashing into the pipe causing what is known as resonance.

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.
the vibrations made by the tuning fork cause the paper to preduce a humming sound.
Lower frequency equates to a longer wavelength, so the 340 Hz tuning fork would emit a longer wavelength sound.
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.
When a tuning fork vibrates over an open pipe and the air in the pipe starts to vibrate, the vibrations in the tube are caused by resonance.

A tuning fork .
A tuning fork struck result in free vibrations.
by the cycle of a tuning fork.
Because of the tuning fork's vibrations. It creates compressional sound waves.
the vibrations made by the tuning fork cause the paper to preduce a humming sound.
Vibrations are transferred from one to the other through the air. If the two have the same frequency (or a very similar frequency), resonance will occur.
Lower frequency equates to a longer wavelength, so the 340 Hz tuning fork would emit a longer wavelength sound.
