Frequency of GW Arm Length Change: Properties & Detailed Explanation

In summary, the conversation discusses the relationship between properties and the frequency at which the lengths change of the arm. It is mentioned that gravitational waves are produced when sources change from being longer in one direction to being longer in the perpendicular direction, with the frequency being twice the orbit frequency for two orbiting bodies. The conversation also touches on the complexity of gravitational waves and suggests a Wikipedia page and a book chapter as resources for further understanding at a technical level.

What properties have to do with the frequency at which the lengths change of the arm?
Also does anybody have a body paper or webpage which explains the properties at a detailed level?

A gravitational wave is typically produced when sources change from being longer in one direction to being longer in the perpendicular direction. If the sources are two bodies orbiting one another, the frequency is twice the orbit frequency (as the system reaches maximum elongation in a given direction twice per orbit).

Gravitational waves involve complex mathematics, usually based on a linear approximation to General Relativity. For an introduction, see this Wikipedia page: https://en.wikipedia.org/wiki/Gravitational_wave

There are plenty of papers on this subject, but they won't be at a "B" level (high school level), which is how you labeled this thread. If you want answers at a more technical level, let me know and I can adjust the thread level accordingly.

Yeah could you please move the thread up a level? Thx

I have changed the thread level to "I".

A good introduction to the theory of gravitational waves is in Chapter 6 of Sean Carroll's online lecture notes on GR:

This is a good text in general for learning GR as well.

What is the frequency of GW arm length change?

The frequency of GW arm length change refers to how often a gravitational wave causes a detectable change in the length of the arms of a gravitational wave detector, such as the Laser Interferometer Gravitational-Wave Observatory (LIGO).

What are the properties of GW arm length change?

The properties of GW arm length change include the amplitude, frequency, and duration of the change, as well as the direction and polarization of the gravitational wave.

How is GW arm length change measured?

GW arm length change is measured using interferometry, which involves splitting a laser beam and sending it down two perpendicular arms of a detector. If a gravitational wave passes through the detector, it will cause a slight change in the length of the arms, which can be detected by measuring the interference pattern of the returning laser beams.

What factors affect the frequency of GW arm length change?

The frequency of GW arm length change can be affected by the distance and mass of the objects that are creating the gravitational waves, as well as the orientation and strength of the waves themselves.

Why is it important to study the frequency of GW arm length change?

Studying the frequency of GW arm length change can provide valuable information about the sources of gravitational waves and the nature of gravity itself. It can also help us better understand the universe and the events and objects that create these ripples in spacetime.
