The behavior of EM radiation and its interaction with matter depends on its frequency, and changes qualitatively as the frequency changes . Lower frequencies have longer wavelengths, and higher frequencies have shorter wavelengths, and are associated with photons of higher energy.
Read moreWhy electromagnetic spectrum is important in astronomy?
Discovered more than a century ago, the electromagnetic spectrum is the basis on which our universe operates . Without it we wouldn’t be able to see, stars wouldn’t shine, and life would not exist. It is one of the most important principles that governs everything around us.
Read moreHow is the electromagnetic spectrum used in space?
Astronomers use the entire electromagnetic spectrum to observe a variety of things. Radio waves and microwaves – the longest wavelengths and lowest energies of light – are used to peer inside dense interstellar clouds and track the motion of cold, dark gas .
Read moreWhat is the difference between L band and C-band?
L-band, or long band, is a wavelength band immediately adjacent to the Conventional band (C-band) initially used to expand the capacity of terrestrial DWDM optical networks. It is now being introduced to submarine cable operators to do the same thing—expand the total capacity of a submarine cable.
Read moreWhat will C-band be used for?
C-band is currently used for the “satellite downlink ” for broadcast television distribution.
Read moreWhat electromagnetic frequency is harmful to humans?
Most mobile operators use from radiofrequency waves in the range up 300 MHz to 3 GHz that can be harmful for human health (1).
Read moreWhat causes electromagnetic frequency?
Electromagnetic radiation is produced whenever a charged particle, such as an electron, changes its velocity —i.e., whenever it is accelerated or decelerated. The energy of the electromagnetic radiation thus produced comes from the charged particle and is therefore lost by it.
