Examples from the web for radio waves
  • Warped radio waves may satisfy the ballooning demand for spectrum space.
  • They're much smaller because the wavelengths they interact with are much shorter than radio waves.
  • After all, the radio waves carrying the time signal must travel at the speed of light, regardless of the satellites' speed.
  • radio waves falling on a radio antenna create electric currents at different frequencies.
  • Microwaves are high freq radio waves, nothing to do with photons.
  • Different frequencies of radio waves could then put some of the atoms in superposition and flip the spins of others.
  • When the length of the antenna is changed by stretching it, however, the device responds to different frequencies of radio waves.
  • That's because radio waves do not travel well through water.
  • The signal strength at any point in a network is the sum of all the paths the radio waves can take to get to the receiver.
  • Prior to the first measurements of radio waves, nobody could prove their existence.

radio waves in Science
radio wave  
A very low frequency electromagnetic wave (from roughly 30 kilohertz to 100 gigahertz). Radio waves are used for the transmission of radio and television signals; the microwaves used in radar and microwave ovens are also radio waves. Many celestial objects, such as pulsars, emit radio waves. See more at electromagnetic spectrum.

radio waves definition


Waves at the end of the electromagnetic spectrum with the lowest frequency (less than 300 megahertz) and the longest wavelength (from a few feet to many miles). Because of their low frequency, radio waves carry very little energy compared to other electromagnetic waves. (See Planck's constant.)

Note: Radio waves can pass through the atmosphere and therefore are very useful for communication. Commercial, short-wave, and citizens' band radio are broadcast with radio waves, as is television.
