Gravity Wave - Wavelength / Freq

Click For Summary
SUMMARY

Gravitational waves have not yet been measured accurately enough to determine their wavelength and frequency at the quantum scale. Current detection efforts by LIGO and LISA focus on frequencies ranging from 2 Hz to approximately 4000 Hz, corresponding to wavelengths of about 500 km. The expected signals primarily originate from binary black hole mergers, characterized by a "chirp" signal. The discussion highlights the misconception regarding the Planck scale, clarifying that gravitational waves are not anticipated to be detected at such small scales.

PREREQUISITES
  • Understanding of gravitational wave physics

Hi Folks

Does anyone know if Gravity waves have been measured accurately enough to have a wavelength and frequency at the quantum scale.

I'm looking for any data measured in Plancks.

Bit of a random one, it relates to some research I am doing at the moment.

Thanks

Physics news on Phys.org
Not only have gravitational waves NOT been measured "accurately enough", it also has NOT been detected YET!

You need to go to LISA and LIGO webpages, for example, and gather your information. Shouldn't you need that to include in your "research"?

Thanks for the quick answer Zapper,

I figured as much, they will be detected I'm sure.

I'm expecting a wavelength of 4 - 16 P. I'm just hoping for the confirmation. If it is discovered (hopefully soon) and it is within this range, I'm going to be a very excited bunny :)

The decteced wavelength will strongly depend on the source emitting the gravitational wave. One of the most likely signals to be detected should origin from binary black hole inspiralling onto each other. The signal should have a characteristic "chirp" form towards the end with strongly increasing frequency (decr. wavelength). A likely range should be 295 to 2000Hz for 20 Solar mass black holes. That would correspond to wavelengths of roughly 1000km.
What unit is P supposed to be?
The frequency range on LIGO is 2 to ca. 4000 Hz, so the smallest detectable waves will have wavelengths of 500km.
 
I'm guessing that "P" might be what the OP called "Plancks". If this is the Planck length scale, boy is he/she seriously off track!

Thanks Betel for the information.

Welcome lowing. It would be nice if you in return answered my question about P.
 
Yes it was Planck lengths, I'm way out it seems :)

I was simply wondering if anybody had theorized or suggested very small gravity waves with a wavelength at a scale smaller than primary particles, it was just a spin off idea from something else I was doing. The references Naty posted (thanks btw) looked interesting, so i'll check that out. I'm going to check out the LISA and LIGO webpages as suggested.
