9 Properties of Radio Waves

Property 1: Radio waves are a form of radiation known as electromagnetic waves. The wavelength of radio waves is longer than the infrared light.

Property 2: Radio waves can travel for a long distance.

Property 3: Radio waves can penetrate through materials.

Property 4: Radio waves cannot be felt and they are invisible.

Property 5: They travel at the speed of light in vacuum. When they travel through the materials the speed differs, depending on the object’s permeability and permittivity.

Property 6: The wavelength range of radio waves is from thousands of metres to 30 cm. These correspond to a frequency from 3 Hertz to 109 Hertz.

Property 7: Radio waves are emitted naturally by lightning and astronomical objects that have a changing magnetic field. They are also created by varying electric currents.

Property 8: Radio waves experience reflection, refraction, absorption, diffraction and polarisation.

Property 9: Radio waves have both electric and magnetic components.
