Technician exam question T3B12
Subelement T3, RADIO WAVE PROPAGATION· Group T3B
T3B12
Which of these frequencies travels at the highest velocity in free space?
- A.Microwaves
- B.UHF
- C.VHF
- D.All radio frequencies travel at the same velocity (correct answer)
WhyAll radio frequencies travel at the same velocity in free space. Every radio frequency, from the lowest amateur allocations up through microwaves, travels at the same speed in free space, the speed of light; frequency affects wavelength, not velocity, answer D. A, B, and C each wrongly single out one frequency range as somehow faster than the others.
