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 !..."
What else can I help you with?
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
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.
All waves make up the electromagnetic?
No, not all waves make up the electromagnetic spectrum. The electromagnetic spectrum consists of a continuous range of electromagnetic waves that vary in wavelength and frequency, including radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, and gamma rays. Other types of waves, such as water waves or sound waves, are not part of the electromagnetic 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.
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
What are the other members of the electromagnetic spectrum?
The other members of the electromagnetic spectrum include radio waves, microwaves, infrared radiation, visible light, ultraviolet radiation, X-rays, and gamma rays. Each of these types of electromagnetic radiation has different wavelengths and frequencies.
What is the comparison between the size of the visible light spectrum and the size of the electromagnetic spectrum?
The visible light spectrum is a small portion of the electromagnetic spectrum, covering wavelengths from approximately 400 to 700 nanometers. The electromagnetic spectrum, on the other hand, includes a much broader range of wavelengths, from gamma rays to radio waves, spanning from very short wavelengths to billions of meters long.
Why is sound not part of the electromagnetic spectrum?
Sound is a mechanical wave that requires a medium, such as air or water, to propagate. Electromagnetic waves, on the other hand, do not require a medium and can travel through a vacuum. This fundamental difference in how they travel means that sound is not considered part of the electromagnetic spectrum.
Sound is not part of the electromagnetic spectrum because?
because sound waves are not a electromagnetic waves because they need a medium for travel....hence electromagnetic spectrum is based on the electromagnetic waves ..like radio waves , micro waves , etc....
The light that you can see belongs to the visible spectrum?
Yes, the visible spectrum is the portion of the electromagnetic spectrum that is visible to the human eye. It includes wavelengths of light that range from approximately 400 to 700 nanometers. Other parts of the electromagnetic spectrum, such as ultraviolet and infrared light, are not visible to the human eye.
The various types of electromagnetic radiation are distinguished from each other by their?
The various types of electromagnetic radiation are distinguished from each other by their frequency and wavelength. Each type, such as radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, and gamma rays, falls within a specific range of frequencies and wavelengths on the electromagnetic spectrum.
