What Exactly Is a Wave Anyway? We’ve all seen waves on water when it’s disturbed. Suppose there is a buoy in that disturbed ...

Back to our radio signal. The electrons in our wire are moving, but not in one direction. These electrons are moving back and forth. Actually, the wave displayed in the activity is a ...

Astronomers say they have traced a mysterious pulsing in the Milky Way to a surprising source: a dead star locked in a dance ...

The team tracked the signal back to a strange binary system containing a dead star or " white dwarf " and a red dwarf stellar ...

Astronomers have finally traced a strange class of radio signals—long a cosmic mystery—to a binary star system made up of a ...

Standing waves are one of those topics that lots of people have a working knowledge of, but few seem to really grasp. A Ham radio operator will tell you all about the standing wave ratio (SWR ...

Electromagnetic radiation is the general term for the more familiar light and radio waves, but also includes gamma rays, x rays, ultraviolet rays, and infrared. All of these forms of electromagnetic ...

The first steps toward inventing radio involved discovering electromagnetic waves and their potential. Hans Christian Oersted was the first to proclaim, in 1820, that a magnetic field is created ...

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 ...

But de Ruiter didn’t think the star would be able to produce radio waves by itself. Something else had to be instigating it.The pulses differed from fast radio bursts, which are incredibly ...
