AM, or amplitude modulation, was the earliest way of sending voice over radio waves. That makes sense because it is easy to modulate a signal and easy to demodulate it, as well. A carbon ...

our current theories say a pulsar spinning only once every 18 minutes should not produce radio waves. So we thought our 2022 discovery could point to new and exciting physics – or help explain ...

At double the width of our Milky Way galaxy, this jet of radio waves is the biggest ever detected so early in the universe's ...

Astronomers have traced two mysterious fast radio bursts from space to wildly different places, which suggests the phenomenon may originate in diverse ways.

Here’s everything you need to know. Like all cellular wireless technologies, 5G works through radio waves. Radio waves are essentially electromagnetic waves that radiate a certain number of ...

As the star spins, these beams sweep past Earth and produce periodic pulses of radio waves, much like a cosmic ... which is hard to explain with our current understanding of neutron stars.

At double the width of our Milky Way galaxy, this jet of radio waves is the biggest ever detected so early in the history of the universe, astronomers reported Thursday. Radio jets like this are ...

So, instead of using ultrasound, radio waves are used as they travel at 300,000,000 m/s. It works in the same way as sonar but with radio waves in place of ultrasound. A short pulse of radio waves ...

Terahertz electromagnetic waves occupy a middle ground between electronics waves, like microwave and radio waves, and photonics waves, such as infrared and UV waves. For example, mobile phones use ...
