Radio Waves in a sentence

Radio waves main When an electric current flows in a suitably shaped conductor at radio frequencies radio waves can be generated.

Electromagnetic waves Ground waves refer to the propagation of radio waves parallel to and adjacent to the surface of the Earth, following the curvature of the Earth.

Hertz's proof of the existence of airborne electromagnetic waves led to an explosion of experimentation with this new form of electromagnetic radiation, which was called "Hertzian waves" until around 1910 when the term "radio waves" became current.

In his Ultra high frequency (UHF) experiments, Hertz transmitted and received radio waves over short distances and showed that the properties of radio waves were consistent with Maxwell’s electromagnetic theory.

This process of directing artificial radio waves towards objects is called illumination, although radio waves are invisible to the human eye or optical cameras.

Electromagnetic radiation (radio and television) Very high frequency radio waves can be refracted by inversions, making it possible to hear FM radio or watch VHF low -band television broadcasts from long distances on foggy nights.

Radio waves are a small part of a wider electromagnetic spectrum of waves, which all emit energy called electromagnetic radiation.

Two years ago not only gravitational waves from the neutron stars merger were detected, but more conventional telescopes also spotted various kinds of light, or electromagnetic radiation, including X-ray, ultraviolet, infrared and radio waves.

Radio waves are “non-ionizing radiation” (all electromagnetic waves are referred to as “radiation” in physics); because they occupy the bottom of the electromagnetic energy spectrum, they cannot affect the atoms and molecules in our cells.

Often abbreviated “mmWave,” millimeter waves are ultra-high frequency radio waves in the 24GHz to 300GHz range, and are being brought to phones for the first time with 5G.

Other forms of radiation such as radio waves, microwaves, and light waves are called non-ionizing.

The mathematical work of James Clerk Maxwell during the 1850s had shown the relationship of different forms of electromagnetic radiation including possibility of invisible airborne waves (later called "radio waves").

Waves of the electromagnetic spectrum vary in size, from very long radio waves the size of buildings to very short gamma rays smaller than atom nuclei.

Fast radio bursts, or FRBs, are powerful flashes of radio waves, lasting only a few milliseconds, that traverse the vast distance of space.

Artificially generated radio waves are used for fixed and mobile radio communication, broadcasting, radar and other navigation systems, satellite communication, computer networks and innumerable other applications.

Electromagnetic wave (radio) main Wireless telegraphy dates as far back as Faraday in the early 19th century, when it was discovered that radio waves could be used to send telegraph messages.

Heating caused by absorption of radio waves Every MRI scanner has a powerful radio transmitter that generates the electromagnetic field that excites the spins.

History Early developments render The exploitation of high-frequency radio waves for heating substances was made possible by the development of vacuum tube radio transmitters around 1920.

If you broadcast your plans over radio waves, anyone with a similar radio listening to the same frequency could hear your plans.

In border cities, American TV and radio waves in English (and Spanish) are received as much Spanish-speaking radio and TV stations from Mexico on the US side of the border, thus a bilingual cross-cultural exchange is at work.
