More information about X-ray and radio waves can be obtained from the following points: X rays and Radio waves are two kinds of electromagnetic waves which in some level of a way are able to penetrate the earth’s atmosphere. Radio waves are longer than the other categories of waves since it is easier for them to pass through the Earth’s atmosphere; thus, they are used for relaying voice and any other form of information through the air. On the other hand, X-ray has shorter wavelengths and able to pass through the atmosphere though minerally, but more so, they are absorbed by air molecules. Today, all X-rays originating from astronomical objects are named space-based observatories suggesting that these instruments are able to reach the terrestrial level from space.
