http://www.lutherie.net/2054560.jpg Smallest guitar strummed at last: What does a 10-micron-long guitar sound like?
Physics News Update reports that the Cornell nano-guitar, first built in 1997, has been played for the first time.
Each silicon string of the nano-guitar is roughly 100 atoms wide, so you cant exactly use a pick. Instead, a Cornell University research team used laser light to set the strings in motion, setting off a 40-megahertz twang. Thats 17 octaves higher than a normal guitars sound put another way, a factor of 130,000 higher.
There is no practical microphone available for picking up the guitar sounds, but the reflected laser light could be computer-processed to provide an equivalent acoustic trace at a much lower frequency, Physics News Update says. The laser light could excite more than one string, creating megahertz chords.
Tarpeeksi pieni? :)
