Don't get me wrong, it was indeed a funny comment and I laughed.+1
Timing was perfect, think this guy should be unbanned for shear balls alone...
Come on dudes it xmas (nearly). Take off the Mod caps, kick back and have a few laughs. Stop taking e-life so seriously......:)
It's not the reason he was banned though. Posting false prices to generate interest in his car is muppetry of the highest order. Adverts isn't the easiest of places to mod. 0 -

I'm not posting this to make Faith look bad.
Although, she misrepresented lasers.
I'm only trying to make sure the information provided is accurate and therefor useful to other readers.
So, I apologize if any feathers are ruffled by my correction
lasers do not go pew pew
like some sonic whistle when the energy state inversion collapses inside mirrored chamber.
If the laser cavity vibrates with sound,
the standing wave in the chamber might loss coherency.
Pffft, everyone knows it's not the laser cavity itself that generates the noise. It's the laser beam travelling through the air which causes it. In the same way that lightening traveling through the air heats it causing it to expand suddenly creating a shockwave which we hear as thunder, a laser blast also heats the air as it passes, causing it to expand producing a soundwave. However because lightening bolts are quite long, stretching from the clouds to the ground, they produce a very long disturbance in the air, which makes for a long wavelength, and thus low frequency, which sounds like a deep rumbling. Lasers on the other hand, or at least the typical hand held blaster variety, are typically much shorter, creating a much shorter wavelength, higher frequency noise, which does indeed sound like 'pew pew'.
Assuming you fire it twice.

I am now rescinding my last statement
Pulse lasers after firing may undergo a chemical reaction altering the pressure with in the chamber.
The movement of gasses through valves could indeed produce a whistling sound.
just keep in mind

that's a great argument
I can only say
from my experience
small arcs of electricity produce a lower frequency snap
not a whistling pew
that and
thunder results when expanding air impacts cool air
surrounding the lightning bolt
so the shock wave is perpendicular to the path of the bolt
and the sounds wavelength would be determined by that pressure gradient
not the length of the lightning0 -

i'm gonna refer to musical tesla coils... i don't know what their frequency upper bound is but it's certainly not limited to a lower frequency snap... but hardware limitations ignored the sparks should be able to go as high as you need if my rudimentary understanding of the physics behind them is correct
oh and the actual "ew" in the pew sound is actually the frequency of the sound falling if my perception of it is the same as yours? which would be caused by the doppler effect which is itself caused by motion?0 -
