And that's when we went onto the airwaves.

And radio waves are limited.

These radio waves penetrate through walls.

Radio waves. There's another thing.

Heinrich Hertz, when he discovered radio waves in 1887, he called them radio waves because they radiated.

The energy in an RF current can radiate off a conductor into space as electromagnetic waves (radio waves) this is the basis of radio technology.

The radio scientists measured a frequency shift in the radio waves to and from the spacecraft, while those signals traveled close to the Sun.

Jansky had made a historic discovery, that celestial objects could emit radio waves as well as light waves.

The way we transmit wireless data is by using electromagnetic waves in particular, radio waves.

What's the point of these radio waves that you've found?

So whilst inventing the technology that would usher in the telecommunications revolution, Watson had discovered that the star at the center of our solar system emitted powerful radio waves.

We've got books, buffets and radio waves, wedding brides and rollercoaster rides.

The F2 layer persists by day and night and is the region mainly responsible for the refraction of radio waves.

He then proposed equations that described light waves and radio waves as waves of electromagnetism that travel in space, radiated by a charged particle as it undergoes acceleration.

In 1887, Heinrich Hertz demonstrated the reality of Maxwell's electromagnetic waves by experimentally generating radio waves in his laboratory.

His research there was devoted to propagation of radio waves in the ionosphere.

And then we have the radio waves, they have the issues I've just mentioned.

Vatican Radio, which was organised by Guglielmo Marconi, broadcasts on short wave, medium wave and FM frequencies and on the Internet.

At even lower frequency, the wave is called a microwave, and at still lower frequencies it is called a radio wave.

Electromagnetic waves can be characterized by either the frequency or wavelength of their oscillations to form the electromagnetic spectrum, which includes, in order of increasing frequency and decreasing wavelength radio waves, microwaves, infrared radiation, visible light, ultraviolet radiation, X rays and gamma rays.

I compared the radio waves spectrum the size of it with the size of the visible light spectrum.

This was originally, when radio astronomy began, Mr. Jansky, at the Bell labs, detected radio waves coming from the sky.

Electrons within the plasma sheet generate a strong radio signature that produces bursts in the range of 0.6 30 MHz.

And mind you, most of the energy is not used to transmit the radio waves, it is used to cool the base stations.

Hence, it is relatively easier to measure both the amplitude and phase of radio waves, whereas this is not as easily done at shorter wavelengths.

In 1902, Heaviside proposed the existence of what is now known as the Kennelly Heaviside layer of the ionosphere.

Radio waves are a type of electromagnetic radiation with wavelengths in the electromagnetic spectrum longer than infrared light.

Discovery and utilization Radio waves were first predicted by mathematical work done in 1867 by Scottish mathematical physicist James Clerk Maxwell.

Pulses of radio waves were beamed at the planet using the radio telescope at Arecibo Observatory, and the echoes revealed two highly reflective regions, designated the Alpha and Beta regions.

Radio astronomy is different from most other forms of observational astronomy in that the observed radio waves can be treated as waves rather than as discrete photons.

As a result, radio waves are generated through a cyclotron maser mechanism, and the energy is transmitted out along a cone shaped surface.

Circular Waves 2 other variation of Circular Waves effect.

We can detect sound waves in the atmospheres of sun like stars.

All of these waves, from the lowest frequency radio waves to the highest frequency gamma rays, are fundamentally the same, and they are all called electromagnetic radiation.

Throughout the day, the airwaves were filled with songs repeating the Father of the Nation s message, and reminding Kenyans to follow in his footsteps.

Occurrences This wave pattern occurs often in nature, including ocean waves, sound waves, and light waves.

They said, It's all right, you can detect radio waves from the Sun, but the Sun is the only object in the universe that's close enough and bright enough actually to be detectable. You can easily calculate that radio waves from the Sun are fairly faint, and everything else in the universe is millions of times further away, so it certainly will not be detectable.

Radio and infrared light can penetrate the dust, but the youngest stars may not emit much light at these wavelengths.

Open Source Initiative provides the English translation of the president's address at the International Free Software Forum (FISL).

This enables her to easily ride through the air currents as if she's sliding along on the ocean waves.

In 1998, there were fewer than 100 radio stations in Belarus 28 AM, 37 FM and 11 shortwave stations.

In his classic physics experiments of 1888, Heinrich Hertz proved Maxwell's theory by transmitting radio waves with a spark gap transmitter, and detected them by using simple electrical devices.

In an electromagnetic wave, both the electric field and magnetic field are oscillating but in different directions by convention the polarization of light refers to the polarization of the electric field.

Lauterbur used the idea of Robert Gabillard (developed in his doctorat thesis, 1952) of introducing gradients in the magnetic field which allows for determining the origin of the radio waves emitted from the nuclei of the object of study.

Radio astronomers study radio waves from space using sensitive antennas and receivers, which give them precise information about what an astronomical object is and where it is in our night sky.
