Answer :
Simply put, radio is the category of electromagnetic radiation whose wavelength is effectively seen by ground-based telescopes.
Why ground-based telescopes can effectively observe radio waves' wavelength?
A disturbance that moves through a medium while transferring energy from one point to another is the simplest definition of a wave.
However, in the context of the work described above, the fact that radio waves can pass through the Earth's atmosphere is the only reason that the wavelength of radio waves may be effectively monitored using ground-based telescopes.
In addition to the explanation given above, there are several sorts of waves, such as sound waves, mechanical waves, and transverse waves.
