Best answer


Radio waves are the waves with lowest frequency and largest wavelength and ofcourse the smallest energy in electromagnetic spectrum. As like other electromagnetic waves they are created by oscillation of charges, and they travel through the air at the speed of light. Radio waves have a frequency range of10 kilo Hz to 100 GHz.

  • What are radio waves?

  • Radio waves are a type of electromagnetic radiation, like light or x-rays. Except they have longer wavelengths in the electromagnetic spectrum. The radio waves frequency ranges from as high as 300 GHz down to 3 kHz.

  • What is the speed of radio waves?

  • The speed of radio waves is approximately 186,000 miles per second, which is also the speed of light. The reason that radio waves travel at the speed of light is that they are a type of electromagnetic radiation. Other forms of electromagnetic radiation are X-rays and light.

  • What has the longest frequency of radio waves?

  • Bookmark added to your notes. Radio waves are the waves that are a sort of electromagnetic radiation and have a recurrence with the longest frequency of radio waves from high 300 GHz to low as 3 kHz; however, someplace it is characterized as over 3 GHz as microwaves. At 300 GHz, the frequency of radio waves is 1 mm, and at 3 kHz is 100 km.

  • What is the wavelength of radio waves at 300 GHz?

  • At 300 GHz. the radio waves wavelength is 0.039 in (1 mm), while at 3 kHz the radio waves wavelength is 62 mi (100 km). What is the speed and Size of radio waves?
