Sentences with phrase «produce electromagnetic radiation»

The wiggler directs the electron beam back and forth, or «wiggles» the beam, to make it produce electromagnetic radiation.

They produce electromagnetic radiation across the electromagnetic spectrum at all wavelengths from long - wave radio to the shortest wavelength gamma rays.

The fifth gravitational wave event (GW170817), detected in mid-August 2017, was probably even more important than the first detection because it was the first one whose source also produced electromagnetic radiation we could observe with ground and space - based telescopes.

Not exact matches

These records have raised hopes that, for the first time, scientists may have glimpsed electromagnetic radiation — light — produced in tandem with gravitational waves.

Upon exposing a metallic surface to electromagnetic radiation that is above the threshold frequency or threshold wavelength (which is specific to the type of surface and material), the photons are absorbed and current is produced.

They say that the electromagnetic radiation, which took the form of γ - rays and seemed to exceed what known sources should produce, could be the result of dark - matter particles concentrating near the centre of the Milky Way and then colliding with and annihilating each other.

When two neutron stars collided on Aug. 17, a widespread search for electromagnetic radiation from the event led to observations of light from the afterglow of the explosion, finally connecting a gravitational - wave - producing event with conventional astronomy using light, according to an international team of astronomers.

It was the first cosmic event in history to be witnessed via both traditional telescopes, which can observe electromagnetic radiation like gamma rays, and gravitational wave detectors, which sense the wrinkles in space - time produced by distant cataclysms.

X-rays are produced in X-ray tubes by the deceleration of energetic electrons (bremsstrahlung) as they hit a metal target or by accelerating electrons moving at relativistic velocities in circular orbits (synchrotron radiation; see above Continuous spectra of electromagnetic radiation).

Some of these neutron stars produce the beams of electromagnetic radiation that characterize pulsars.

There is no direct evidence on whether there is an association between electromagnetic radiation produced by wind farms and health outcomes.

There are growing health and safety concerns regarding the widespread use of technology, such as cellular phones and wireless computer networking (WiFi), which produce non-ionizing electromagnetic radiation.
