Why SETI examines radio wave rather than other electromagnetic spectrum?

Because it's assumed that extra-terrestrial life will communicate via the radio-waves part of the spectrum. Having said that - there is no reason why another part of the ES couldn't be used. As one scientist said years ago about contacting aliens - "...They may have already sent us messages - we're probably just not looking in the right place for them !..."

When Studying an object by looking at the visible light and other electromagnetic waves that the object creates is called?
spectrum
Are microwaves good or bad for us?
As with any other wavelength of the electromagnetic spectrum, they can be good or bad depending on the use to which they are put.
Regions of electromagnetic spectrum in order of increasing energy?
Radio wavesMicrowavesInfrared wavesVisible lightUltraviolet lightX raysGamma raysthe other way around for apex
What are two types of electromagnetic radiaction that humans can sense?
Light is the most well known form. However, humans can not sense any other electromagnetic radiation. (e.g. gamma rays x-rays infra-red ultraviolet etc.) the human eye can only see a fraction of the full electromagnetic spectrum.
What is the transfer of energy by electromagnetic waves?
The transfer of energy by electromagnetic waves is called electromagnetic radiation. Light, radio waves and X-rays are a few other examples of this radiation phenomenon. The Transfer process is the "flow" of particles from one location to another. The best visual example is the transfer of "heat" from one source to another.
Find out the properties of x-ryas and compare them with other members of the electromagnetic spectrum?
find out the properties of x-rays and compare them with other members of electromagnetic spectrum
What is the full range of electromagnetic radiation called?
There are seven types of electromagnetic waves and they are: 1. Radio waves 2. Microwaves 3. Infra-red waves 4. (visible) Light waves 5. Ultra-violet waves 6. X-ray waves 7. Gamma rays
Sentence for the word electromagnetic spectrum?
White light, which can split in to the colours is part of the electromagnetic spectrum. Other parts of the electromagnetic spectrum are, cosmic rays, X-rays, UV light, infra red(IR) waves, micro waves, and radio waves. m ic ray of the spectrum
The entire range of em waves is called the?
The total of all electromagnetic waves is called the electromagnetic spectrum. The electromagnetic spectrum includes radio waves, microwaves, infrared radiation, visible light waves, ultraviolet radiation, x-rays, and gamma rays. Only visible light waves, which humans see as the band of colors from red to violet, are the portion of the spectrum visible to the human eye, although many other life forms are sensitive to infrared and possibly to other segments the spectrum.
What kind of wave is an x ray?
X-Rays are part of the electromagnetic spectrum. Other waves on the electromagnetic spectrum include light, radio waves, and gamma rays.
What are the other members of the electromagnetic spectrum?
Other members of the electromagnetic spectrum other than ordinary light are gamma rays x-rays, ultraviolet rays,infrared rays, microwaves, radio waves and TV waves
The various types of electromagnetic radiation are distinguished from each other by their?
Electromagnetic waves are classified according to their wavelength and frequency and this classification is called electromagnetic spectrum.
Where can you find good jokes about the electromagnetic 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.
How is visible light different from the other waves and rays on the electromagnetic spectrum?
It has a different wavelength and frequency.
How is the electromagnetic spectrum useful?
Visible light, which lets humans and other animals see, is part of the electromagnetic spectrum. RF (radio frequency) waves are part of the electromagnetic spectrum. RF transmissions carry radio and television broadcasts. They have the lowest frequency. Microwaves are part of the electromagnetic spectrum. X-Rays are part of the electromagnetic spectrum and have the highest frequency..
Most sunlight consists of what parts of the electromagnetic spectrum?
The visible spectrum (the radiation we can see as light). This is most likely why organisms evolved to be able to see visible light over other types of electromagnetic radiation - the sun emits this more than the other frequencies, so it was easier for life to evolve seeing this spectrum.
Where in the electromagnetic spectrum are pulsars best observed?
Pulsars are best observed in the radio part of the electromagnetic spectrum. This is because their strong radio emission allows them to be detected and studied using radio telescopes. However, pulsars have also been observed at other frequencies, including X-ray and gamma-ray wavelengths.
