- Radio waves like the one you select to listen in your radio have frequencies in the MHz (mega-hertz, 10^6) region and relatively long wavelengths while light in the visible have higher frequency (~~10^15Hz) and smaller wavelengths: Also, to produce a radio wave you use an antenna that is a piece of conducting wire where you can put the electrons in motion up and down as in a block-spring motion.

Aug 10, 2016 · Since radio waves are longer than optical waves, radio telescopes are made differently than the telescopes used for visible light. Radio telescopes must be physically larger than an optical telescopes in order to make images of comparable resolution.

Where do radio waves fall on the electromagnetic spectrum? Radio waves have the same wavelengths as visible light. Radio waves fall on the high-frequency side of visible light. Radio waves fall on the short-wavelength side of visible light. Radio waves fall on the low-frequency side of visible light.
Electromagnetic radiation with a wavelength between 380 nm and 760 nm (400–790 terahertz) is detected by the human eye and perceived as visible light. Other wavelengths, especially near infrared (longer than 760 nm) and ultraviolet (shorter than 380 nm) are also sometimes referred to as light, especially when the visibility to humans is not ...

The electromagnetic spectrum describes all of the kinds of light, including those the human eye cannot see. In fact, most of the light in the universe is invisible to our eyes. The light we can see, made up of the individual colors of the rainbow, represents only a very small portion of the electromagnetic spectrum. Other types of light include rad...
Light travels in waves, much like the waves you find in the ocean. As a wave, light has several basic properties that describe it. One is frequency, which counts the number of waves that pass by a given point in one second. Another is wavelength, the distance from the peak of one wave to the peak of the next. These properties are closely and invers...
To study the universe, astronomers employ the entire electromagnetic spectrum. Different types of light tell us different things. Radio waves and microwaves, which have the lowest energies, allow scientists to pierce dense, interstellar clouds to see the motion of cold gas. Infrared light is used to see through cold dust; study warm gas and dust, a...
Energy types on the electromagnetic spectrum are denoted by wavelength. Infrared wavelengths are longer than those of visible light, while ultraviolet wavelengths are shorter. Ultraviolet radiation has shorter wavelengths than visible light, comprising the 100-400 nm part of the spectrum.
As noted before, an electromagnetic wave has a frequency and a wavelength associated with it and travels at the speed of light, or c. The relationship among these wave characteristics can be described by vw = fλ, where vw is the propagation speed of the wave, f is the frequency, and λ is the wavelength.
