Higher frequencies mean faster data transfer and more powerful processors. Technically, however, it is anything but easy to keep increasing clock rates and radio frequencies. New materials could solve ...

Components of a typical laser include gain medium, laser pumping energy and resonant optical cavity. The output frequency of most lasers is fixed or within a small range, and it is difficult to ...

Modern technology uses many frequencies of electromagnetic radiation for communication, including radio waves, TV signals, microwaves and visible light. Now, a University of Utah study shows how ...

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 ...

What is Electromagnetic Radiation? When you sit in front of a computer or television, you are being bombarded by harmful waves quietly emanating from it. Even if you turn off the device, your ...
