It does get louder! It increases the amplitude of the sound wave
the vibrations made by the tuning fork cause the paper to preduce a humming sound.
Put it by something which will resonate in sympathy with it, such as a soundbox or sympathetic string. If electricity is an option, electrical amplification can make a sound as loud as needed.
it amplifies them because the table vibrates as well as the tuning fork
A tuning fork combined with a quartz sound magnet.
The sound would be muted if a tuning fork is hit and then placed into a cupboard.
A guitar is a far more complex structure than a tuning fork, and has more harmonics. The whole design of a tuning fork is intended to give as simple and pure a sound as possible, since that is the easiest type of sound to use when you are trying to tune an instrument. You wouldn't want harmonics in a tuning fork.
Because of the tuning fork's vibrations. It creates compressional sound waves.
300Hz is the natural frequency of the tuning fork hence if a sound wave of same frequency hits the fork then RESONANCE occurs
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.
The air experiences a longitudinal pressure wave, which some might call a vibration, as it transmits sound from a tuning fork to the ear.
The characteristics that determine the frequency with which a tuning fork will vibrate are the length and mass of the tines.
