frequencies

These frequencies imitate naturally occurring frequencies that happen in our brain every day and whichever frequency you listen to will give you the desired affect that the frequency is associated with.

FWiW you can have 3 or even more frequencies in a laser beam coherent with each other, i.e.

Cryptographers can figure out words by simply looking at their frequencies in a large body of text.

You want to visualize your signals and frequencies for debugging purpose, how do you quickly visualize them?

They are frequencies that are played in each ear that must be listened to with headphones in order to work.

They have specific frequencies they can use that do not interfere with military or other use.

It seems like the firefighters should have a device to disrupt the radio frequencies of the drones in these cases.

They have the ability to cancel out imperfections in the road surface over a wide range of frequencies and amplitudes.

That, and the wide-spectrum jammers they require (2.4, 900mhz, what else do they use?) would probably wreak havoc on operational frequencies.

Other (also airborne) instruments operate at higher frequencies, trading higher resolution for less penetration.

So if this is just creating white additively using RGB lasers, won't it be more like 3 frequencies, not a full spectral band?

In wavelets errors in lower frequencies have ripple ( wink ) effects.

Each headphone plays a different frequency and you heard the difference between those two frequencies, created the "beat" sound.

All those "gorgeous" colors and structures are added by computers shifting frequencies we can't see into visible range colors.

A true "white" laser would be coherent on all frequencies, but I'm guessing that's pretty hard to accomplish (so limited holography uses).

They mention that the various "components" could be tuned as necessary to generate different frequencies if needed, but the RGB was kind of their proof of concept.
