Light and CPUs
hey, as you know light's frequency is around 9GHZ, so heres a question, what will happen if a cpu were to match or exceed that frequency?  |

I'm no expert but surely light has differing wavelengths depending on the type ie. UV and IR. Differing wavelengths mean differing frequencies.

right, even different colors of light will have different frequencies, 9ghz was rounded and based on plain light

actually its funny that you mention that.
Intel has figured out how to mount fiber optics(or was it lasers?) onto silicon and they expect that by around 2010, our processors will be using light beams rather than electrons for processing.

wonder how hot they will run...  |

using light would probably be alot cooler than using electrons imo…

Samething that happened when we hit "800MHz" or supposedly Microwaves

Aah, that explains why I grew a second head shortly after upgrading to my new cpu then.  |

Actually, not quite 9 GHz . . . .
Visible light's wavelength is roughly 400-800 nanometers
The wave equation states:
Code:
speed = wavelength x frequency
So, plug in the speed of light (3x10^8 meters/second) and wavelength range 4x10^-7 to 8x10^-7 . . .
and you end up with the frequency of visible light being roughly from 375,000 to 750,000 GHz

i think 9GHz is the low end of the ifnrared spectrum, actually...meaning maybe PCs will now cause cancer?

frequency has nothing to do with speed... as in the speed of light
frequency of a cpu is different to the frequncy of a wave in a beam of light |

9 GHz is about = RADAR frequency
Anyway, tastyweat is right, CPU's and light are apples and oranges |

not when CPUs are going to be using light.
Also remember that the frequency is around 200mhz on your processor. When it says "3ghz" it really means 200mhz*15, not 3 actual ghz.
just some food for thought. |
