Why are X-rays not used for communication?
Unlike the long wavelength radio waves and stuff, these short wavelength and high energy radiation get attenuated (loose energy by interacting with the air or whatever comes in the way) very fast. Hence not useful in communication.
What Ray is used for communication?
Radio waves
Radio waves are used for communication such as television and radio. Radio waves are transmitted easily through air. They do not cause damage if absorbed by the human body, and they can be reflected to change their direction. These properties make them ideal for communications.
What is XRAY communication?
X-ray communication (XCOM) is a special type of wireless optical communication, which also has the advantage of low divergence and high bandwidth [9]. XCOM uses modulated X-ray beams as a carrier for data transmission and is considered to be the next-generation aerospace communications technology [10].
Are gamma rays used in communication?
Gamma rays have quite a bit more energy than regular light, and their wavelength is a lot shorter too—both attributes that could make them an ideal candidate for better data communications and other physics applications. Unfortunately, they are not as easy to produce and harness as regular light.
Why do you think gamma rays Cannot be used for communication in the same way radio waves are used?
Gamma rays of this power are utterly lethal to any biological system in their path. Moreover, their high photon energy means that they interact with and are swiftly (in comparison with radio broadcast distances) absorbed by air. They would be useless for terrestrial communications from this last point of view also.
Can microwaves be used for communication?
Microwaves are widely used for point-to-point communications because their small wavelength allows conveniently-sized antennas to direct them in narrow beams, which can be pointed directly at the receiving antenna.
How do you communicate with space?
Messages travel through space as radio waves, just like the radio waves that you receive with a car radio. Each spacecraft has a transmitter and a receiver for radio waves as well as a way of interpreting the information received and acting on it.
How do space stations communicate?
If someone does need to “call” the ISS, operators at mission control centres simply relay the audio through a telephone line to Houston into the very high frequency space-to-ground radio network. The phone number at NASA Johnson Space Center is +1 281-483-0123, but your chances of getting through to the ISS are slim.
What are dangers of gamma rays?
Gamma rays have so much penetrating power that several inches of a dense material like lead, or even a few feet of concrete may be required to stop them. Gamma rays can pass completely through the human body; as they pass through, they can cause ionizations that damage tissue and DNA.
What can gamma rays be used for?
Gamma rays are used in medicine (radiotherapy), industry (sterilization and disinfection) and the nuclear industry. Shielding against gamma rays is essential because they can cause diseases to skin or blood, eye disorders and cancers.
Why are X-rays and gamma rays not used for communication?
Actually, NASA and others are considering the use of X-rays as a communication medium. The difficulty comes in the modulation, and in the fact that X-rays can’t be transmitted via wires or fiber. But for vehicles re-entering Earth’s atmosphere, X-rays provide a benefit in that they aren’t stopped by the ionizing effects of re-entry.
Why do we use X-rays instead of visible light?
But for vehicles re-entering Earth’s atmosphere, X-rays provide a benefit in that they aren’t stopped by the ionizing effects of re-entry. X-rays are also more difficult to focus than visible light. Even though the energy is carried in photons, the higher energy photons don’t react in the same way to optical elements.

How are X-rays used in deep space communication?
One advantage that XCOM has compared to laser communication in deep space is that X-rays have shorter wavelengths than the visible or infrared light typically used in laser communication. This means that, in principle, XCOM can transmit more data for the same amount of power that laser communication requires, Gendreau said.
