A mysterious and powerful burst of radio waves reached Earth after traveling through space for 8 billion years dubbed FRB ...

There's lots to discover in the electromagnetic spectrum. Here's a tour that begins with radio waves and takes you through microwaves, infrared radiation, light, ultraviolet radiation, and X-rays.

UK smartphone users will soon be able to make and receive phone calls via satellites under new proposals from Ofcom. The ...

Figure caption, Each region of the electromagnetic (EM) spectrum has a range of wavelengths associated with it. Radio waves have the longest wavelengths and gamma rays have the shortest wavelengths.

The Doppler Effect shifts the frequency of the radio waves to higher (moving toward us) and lower (moving away) frequencies. The resulting spectrum (power vs. frequency) shows two peaks. These ...

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 ...

Terahertz (THz) waves are located between microwaves and infrared light in the electromagnetic spectrum. They can pass ...

The electromagnetic spectrum is a continuous range of wavelengths ... signal to be transmitted and received. Bluetooth uses radio waves because radio waves pass through walls but the signal ...
