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.

  • Do radio waves travel at the speed of light?

  • At 300 GHz, the frequency of radio waves is 1 mm, and at 3 kHz is 100 km. They travel at the speed of light simply like all other electromagnetic speeds of radio waves do.

  • What is the range of radio waves?

  • Radio waves are a type of electromagnetic radiation with frequencies ranging from 300 GHz to as low as 3 Hz, and wavelengths ranging from 1 millimeter (0.039 inches) to 100 kilometers (62 miles). Similar to all other electromagnetic waves, they travel at the speed of light.

  • What is the relationship between wavelength and frequency of radio waves?

  • The length of a radio wave is important and must be taken into consideration when designing communication systems. The mathematical relationship of frequency and wavelength is: Where is the wavelength given in miles, V is the velocity of the wave given in miles per second, and f is the frequency in hertz.
