Gravity Waves: Frequency & Understanding Needed

Click For Summary

Discussion Overview

The discussion revolves around understanding gravitational waves, specifically their frequency and the challenges associated with calculating it. Participants explore the complexities of gravitational wave frequencies based on different astronomical sources.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • One participant mentions having a solution for a simple ordinary differential equation (ODE) related to gravitational wave frequency but seeks further understanding of gravitational waves.
  • Another participant questions the nature of the "simple ODE" referenced.
  • It is proposed that gravitational waves do not have a specific frequency, as their frequency depends on the sources, with examples given of frequencies ranging from 10^-3 Hz to 100 Hz for dense star pairs and from 10^-10 Hz to 10^-2 Hz for supermassive black holes.
  • A reference to a 1995 paper by Kip Thorne is provided, which suggests a frequency range for gravitational waves from 10^-16 Hz to 10^4 Hz, with a noted period of 10^-16 Hz equating to approximately 300 million years.
  • One participant expresses intent to study the topic further and develop a simple equation for calculating gravitational wave frequency, promising to return with findings.

Areas of Agreement / Disagreement

Participants exhibit differing views on the nature of gravitational wave frequencies, with no consensus reached on a specific frequency or method for calculation. The discussion remains unresolved regarding the best approach to understanding and calculating these frequencies.

Contextual Notes

Participants note the difficulty in calculating gravitational wave frequencies and the dependence on various astronomical sources, highlighting the complexity of the topic.

I got one solution for an simple ode that involving gravity wave frequency . Before going further I have to understand more about gravity wave . So I need your help guys ...

What was that "simple ode"?o_O
 
Hi,
Gravtiational waves don't have any specific frequency, and it's definitely not easy to calculate the frequency though any simple equations. The frequency of the gravitational wave depend on the sources they originate from. For instance, gravitational waves originating from a pair of dense stars would have a frequency ranging from 10 to the power of -3 Hz all the way to 100 Hz, or a pair of supermassive black holes would have a frequency ranging from 10 to the -10 Hz all the way to 10 to the -2 Hz. As you can see that is quite a large range, so I'm sorry but it would be extremely difficult to calculate this value. On the other hand, if you want to know more about gravitational waves, there are many books containing great information, so I would say visit your local library and hope that they have books on them. If not, you may want to find an eBook or an online source.

This 1995 Kip Thorne paper, Gravitational Waves (http://arxiv.org/abs/gr-qc/9506086), expects them in the range of 10^-16 Hz to 10^4 Hz. The period of 10^-16 Hz is about 300 million years.
 
I'll study this more and maybe develop a simple equation for calculating this value, once I am complete I'll get back to you on it and give you the equation(s). :D
