Sentences with phrase «electromagnetic radiation such»

Dark matter is an unseen substance that does not, as CERN explains, absorb, reflect or emit electromagnetic radiation such as light.

A standard atomic clock takes advantage of the fact that an atom can absorb electromagnetic radiation such as light at certain frequencies as its internal structure jumps from one «quantum state» to another.

When a unit of electromagnetic radiation such as a microwave hits an electron, it absorbs it and changes position.

Not exact matches

They also make great play of more contentious issues such as the effects of electromagnetic radiation.

Electromagnetic radiation is the fastest and also by far the cheapest method of establishing such contact.

His theoretical research focuses on novel optical effects such as so - called transformation optics — bending light in curious ways with metamaterials, or assemblages of rods and rings smaller than a wavelength of electromagnetic radiation.

The finding that a single layer of atoms modifies properties of light and other electromagnetic radiation has implications for controlling light at subwavelength scales in photonic devices such as LEDs and photovoltaic cells.

GW170608 is the lightest black hole binary that LIGO and Virgo have observed — and so is one of the first cases where black holes detected through gravitational waves have masses similar to black holes detected indirectly via electromagnetic radiation, such as X-rays.

So far, astronomers and physicists have investigated the universe using electromagnetic radiation, such as infrared, X-rays and gamma rays.

They also include less - visible sources, such as radiation and electromagnetic stressors from cell phones and towers.

Further, electromagnetic radiation (such as that emitted by Wi - Fi, cell phones, cell towers and «smart» meters) may affect the body like light does at night — and inhibit melatonin production.

At a special facility in Michigan, NHTSA and NASA engineers bombarded vehicles with electromagnetic radiation to study whether such radiation could cause malfunctions resulting in unintended acceleration.

There has to be some sort of inhomogeneity, such as free surface, cloud droplet, dust particle or abrupt change of refractive index, for the energy in the intercepted electromagnetic radiation to reappear in the form of translational motion (i.e. heat) rather than being confined to vibrational and rotation modes.

Well again the science is simple, electromagnetic radiation comes in different wavelengths (sycles) and in return different frequencies, which determines the intensity and penetrating ability... such as gamma rays being able to penetrate solid lead because it is at the high end of the frequency range.

The radiant heat component is — presumably — just objects such as humans being directly warmes by the electromagnetic direct radiation from the sun, especially the IR component.

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.
