WebNov 14, 2014 · Most of the radio part of the EM spectrum falls in the range from about 1 cm to 1 km, which is 30 gigahertz (GHz) to 300 kilohertz (kHz) in frequencies. The radio is a very broad part of the EM spectrum. Infrared … WebAn important point to note is that two waves with different wavelengths can have the same frequency. So lets assume, that Wave 1 has a wavelength of 1 cm and Wave 2 has a wavelength of 2 cm. To have the same frequency, Wave 2 will need to travel at a speed that is 2 times Wave 1.

WebApparently, the peaks of both the amplified seed pulse and the newly generated pulse can exit faster than a reference beam traveling at the speed of light in a vacuum. The speed differences they reported were 50 to 90 nanoseconds faster than light through a vacuum. WebGenerally speaking, we say that light travels in waves, and all electromagnetic radiation travels at the same speed which is about 3.0 * 10 8 meters per second through a vacuum. We call this the "speed of light"; nothing can move faster than the speed of light.
