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

Radio waves. There's another thing.

And radio waves are limited.

These radio waves penetrate through walls.

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?

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

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

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

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

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

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.

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

Stephen Hawking I think it quite likely that we are the only civilization within several hundred light years otherwise we would have heard radio waves.

The planet became an intense emitter of radio waves the total output from all TV and cell phones and radar transmissions. And something else happened.

The Ministry of Posts and Telecommunications plans and promotes policies governing the use of radio waves and space related research and development in the same field.

The Corporation was established in 1979 to develop radio communications and seek effective utilization of radio waves in space by controlling the location, attitude etc. of communications and broadcasting satellites and efficiently using the telecommunications facilities installed on those satellites.

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.

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.

Now you have to remember, this is 10 years before Heinrich Hertz proved the existence of radio waves 15 years before Nikola Tesla's four tuned circuit nearly 20 years before Marconi's first broadcast.

Thought he could turn back the waves couldn't turn back the waves.

New partnerships, for example, include Radio 10 in Guatemala, Radio Post Phillip in Australia and Communidad 100 in Argentina and three more stations in China Radio Sichuan, Radio Lianing and Radio Ji Lin.

These are the beautiful waves.

Waves crashing against the coast.

And we put them in, and what you see immediately is that there are waves and waves of innovation.

The word tsunami is a term that derives from an old Japanese word meaning harbour waves or port waves .
