Description
Podnami builds that rocket...also Matt wasn't shaken or anything at the rejection of his first fact but what he MEANT to say for his second was light is made up of photons, which are each a packet of energy in an electromagnetic wave. Radio, X-rays, gamma rays, infrared, visible light, ultraviolet, etc. are all the same thing, photons, but at different energies. Lower energy, longer wavelength. So while what we call a radio wave might have a wavelength from a few centimeters to hundreds of meters, visible light has wavelengths between 450 and 700nm (nanometers, which is 10^-9 meters). UV, X-rays, and gamma rays have even more energy and shorter wavelengths. Photons are created by wiggling charged particles back and forth. In an antenna, electrons are moved from one end of the antenna to another at the proper speed to emit photons of the desired frequency. So an AM broadcast radio antenna may shake them at around one million times per second, where your WiFi router does so at 2.45 billi
