Electromagnetic waves travel at 300,000,000 metres per second (m/s) through a vacuum. Often a phrase is used to help remember the order of the groups of the electromagnetic spectrum such as Roman ...

Electromagnetic waves are members of a family of waves with common properties called the electromagnetic spectrum. The electromagnetic spectrum is a continuous range of wavelengths. The types of ...

Did you know that the world around us is filled with different types of light waves ? From the warm glow of the sun to audible radio waves and invisible gamma rays, electromagnetic waves (action ...

Although you might not think of them in this way, you are in possession of two extraordinary antennas, perfectly tuned to receive a narrow band of electromagnetic radiation. These antennas are not ...

A new patterned spintronic emitter enables room-temperature control of terahertz wave polarization.

Humans typically blink 4 times per second, equivalent to a frequency of 4 Hz. Blinking at a rate of 1 billion times per second, or 1 GHz, is not possible for a human being. But this is the current ...

As a major UMass Lowell research facility, the Submillimeter-Wave Technology Laboratory's (STL) primary mission is to engage with UMass Lowell students, faculty, and external sponsors to develop novel ...

All forms of electromagnetic radiation, whether they're called waves or rays, are generated by particles in motion. In a radio signal, for example, negatively charged electrons quickly move back ...

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