Bookmark or Share- general relativity - How are gravitational waves exactly produced ...Gravitational waves are generated in a manner analogous to electromagnetic waves. Classically, changing electric or magnetic fields can generate electromagnetic waves, a radio antenna being a good example, and also radiation is emitted by accelerating or decelerating particles.
- Do gravitational waves travel faster than light?As far as I know, gravitational waves are not absorbed & reemitted and therefore travel with the speed of light in vacuum c as opposed to EM-waves which travel at a speed c/n. At the bottom of this link is an example of how you could calculate the refractive index in space for radio waves: link (Edit: Please note that the link uses a different ...
- Gravity vs Gravitational Waves - Physics Stack ExchangeGravity is a fundamental force between masses, but gravitational waves are just a secondary effect related to the dynamics of a gravitational system in certain circumstances. Whether gravity is transmitted instantaneously or not has been a controversial issue since Laplace.
- Gravitational waves frequency - Physics Stack ExchangeThe gravitational waves that were detected swept up in frequency and amplitude from an undetectable level at a few tens of Hz to abut 150 Hz as the black holes merged. This is known as a "chirp". Gravitational wave sources might have a variety of frequencies. For binary systems, the principle gravitational frequency is twice the orbital frequency.
- What is the difference between gravitons and gravitational waves?In physics, gravitational waves are ripples in the curvature of space-time which propagate as waves, travelling outward from the source. Predicted in 1916 1 by Albert Einstein to exist on the basis of his theory of general relativity, 3 gravitational waves theoretically transport energy as gravitational radiation.
