Electromagnetic radiation in the frequency range between roughly 0.5 - 100 GHz.
Loosely known as "radio".
Radio Waves
infra-red telescope is a telescope in which you can look at everything in the waves of infra-red.
The most powerfull type of telescope is the Radio telescope. Radio waves travel much further than light waves.
A Radio Telescope (eg Jodrell Bank and Aricebo).
Radio telescopes are designed to detect sources of electromagnetic radiation such as x-rays or other invisible emissions. They detect electromagnetic radiation from distant galaxies, including stars and planets and other astronomical radio sources. They are usually in the form of large parabolic antennas, sometimes with hundreds linked together in enormous arrays, connected to extremely sensitive radio frequency receivers.
It is electromagnetic radiation in the radio par of the spectrum.
It is electromagnetic radiation in the radio par of the spectrum.
The 4C array is a type of radio telescope that is a cylindrical paraboloid. One can find this telescope at the Mullard Radio Astronomy Observatory in Cambridge, England.
radio wave
Radio frequency radiation can be defracted by hills.
Radio
Power frequencies has a low frequencies of 60 to 50 hertz, it is weak radiation from ac circuits.
