The waves are called "electromagnetic waves". All types of EM waves can be used to study the Universe.
.
Between UVB and Gamma rays.
Wavelenghts of visible light: 390-780 nm (after CIE).
Stars are like the bread crumbs left by the Big Bang. By studying stars scientists get to know the elements that are found in them and how are they connected to us. They also teach us the way the universe works. They illuminate the darkest secrets of the universe.
electromagnetic waves
That energy is called "electromagnetic waves" or "electromagnetic energy".
Electromagnetic spectrum is formed due to the difference of wavelengths and frequency of electromagnetic radiations as they are orderly distributed.
.
Yes.
the visible light spectrum
Between UVB and Gamma rays.
Gamma waves :D
Signs piont to no you stupid are somthing?
No, they are a more energetic type of electromagnetic radiation found beyond the blue end of the visible spectrum. Infrared rays are also electromagnetic but have much less energy and longer wavelengths and are found beyond the red end of the visible spectrum.
I found two EM spectrum jokes. Whether they are good, let the reader decide:An XKCD comic about the electromagnetic spectrum (please see the related link)and this (funny?) valentine:Roses reflect a light frequency at one end of the visibleelectromagnetic spectrum,Violets reflect a light frequency at the other end of the visible electromagnetic spectrum,Sugar is C12H22O11,And you release the endorphins in my brain.
The only property that a ray or wave needs to have in order to be located within the electromagnetic spectrum is that it must be an electromagnetic wave. Gamma rays meet that requirement nicely.
Microwaves would be found below infrared radiation, which is below visible light. They'd be at the top of what is called the radio spectrum.
