Optical astronomers use both angstroms (0.00000001 cm, or 10 -8 cm) and nanometers (0.0000001 cm, or 10 -7 cm). Infrared astronomers use microns (millionths of a meter) for wavelengths, so their part of the EM spectrum falls in the range of 1 to 100 microns. Infrared and optical astronomers generally use wavelength. The radio is a very broad part of the EM spectrum. 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. It is much easier to say or write "two kilometers" than "two thousand meters." Generally, scientists use whatever units are easiest for the type of EM radiation they work with.Īstronomers who study radio waves tend to use wavelengths or frequencies. The short answer is that scientists don't like to use numbers any bigger or smaller than they have to. But why have three ways of describing things, each with a different set of physical units?Ĭomparison of wavelength, frequency and energy for the electromagnetic spectrum. Each of these three quantities for describing EM radiation are related to each other in a precise mathematical way. Frequency is measured in cycles per second, or Hertz. Radio waves have photons with low energies, microwave photons have a little more energy than radio waves, infrared photons have still more, then visible, ultraviolet, X-rays, and, the most energetic of all, gamma-rays.Įlectromagnetic radiation can be expressed in terms of energy, wavelength, or frequency. The different types of radiation are defined by the the amount of energy found in the photons. Each photon contains a certain amount of energy. Radio waves, gamma-rays, visible light, and all the other parts of the electromagnetic spectrum are electromagnetic radiation.Įlectromagnetic radiation can be described in terms of a stream of mass-less particles, called photons, each traveling in a wave-like pattern at the speed of light. The biggest gamma-ray generator of all is the Universe.Īre radio waves completely different physical objects than gamma-rays? They are produced in different processes and are detected in different ways, but they are not fundamentally different. Gamma ray: Doctors use gamma-ray imaging to see inside your body. Hot gases in the Universe also emit X-rays. X-ray: A dentist uses X-rays to image your teeth, and airport security uses them to see through your bag. "Hot" objects in space emit UV radiation as well. Ultraviolet: Ultraviolet radiation is emitted by the Sun and are the reason skin tans and burns. Fireflies, light bulbs, and stars all emit visible light. In space, infrared light helps us map the dust between stars. Infrared: Night vision goggles pick up the infrared light emitted by our skin and objects with heat. Microwave: Microwave radiation will cook your popcorn in just a few minutes, but is also used by astronomers to learn about the structure of nearby galaxies. Radio waves are also emitted by stars and gases in space. Along with audio waveforms, you can also add text, subtitles, transitions, and so much more.Radio: Your radio captures radio waves emitted by radio stations, bringing your favorite tunes. After the waveform is added, you can customize its color, style, position, and size. Under the waveform section you can select the waveform style you want and then choose which audio file you want to become your waveform. Just add a video or audio track to your project, then select “Elements” in the left-hand toolbar. Kapwing is a simple but powerful multimedia editor that lets you add audio waveforms to your videos. Many people like having a visual when they are watching something, so by adding a sound wave to your content, it can help your audience stay engaged with the video while they are listening to what is playing.Ĭreating a sound wave is easier than ever. When scrolling through TikTok or YouTube do you ever come across a podcast, lyrics video, or “story time” where you can see the sound waves of what’s being played or talked about? A technical name for these visual sound waves are waveforms and they can add that professional touch your content was needing. Make your music videos, podcast audio, and social posts stand out from everyone's feed. Create a sound wave to visualize music, podcast, or voiceoversīring your audio content to life when you turn it into sound wave art and add a background image to it. Add a sound wave animation to your next audio episode or teaser post and start showing everyone your content. Make your sound wave the way you want by choosing between a classic waveform style or a stacked bars style, and customizing its color, animation, and speed.
