Question 129

Which of these frequencies travels at the highest velocity in free space?

  1. Microwaves
  2. UHF
  3. VHF
  4. All radio frequencies travel at the same velocityBonne réponse

Free space is not dispersive for radio waves, so microwaves, UHF and VHF signals all travel at exactly the same speed. Frequency changes the wavelength, not the velocity.
