NettetA radio wave is made of these same electric and magnetic forces, but it is sent from an antenna (or signal radiator), often with enough power to travel a long distance through space and penetrate solid structures. In empty space, or any vacuum, radio waves spread at the same speed as light. NettetRadio telescopes look toward the heavens to view planets, comets, giant clouds of gas and dust, stars, and galaxies. By studying the radio waves originating from these sources, astronomers can learn about their …

Speed of Radio Waves: How Fast Does Radio Waves Travel?

Nettet4. feb. 2024 · Light waves (that aren't radio waves) are different. They do not require the existence of a medium in order to propagate. So light can travel through the vacuum of space unimpeded. This is why we can … Nettet3. feb. 2016 · The size of a photon’s wave – its wavelength – tells you about its energy. Figure 1 shows waves with two different wavelengths. If the wave is long, it does not have much energy; if it is short, it has a lot of energy. Radio waves do not have much energy, and that means they travel in big waves with long wavelengths. hearthstone battlegrounds seafood slinger

If you want to think in terms of a wave (such as a radio or light wave) then energy is proportional to amplitude (actually the square of the amplitude) and also proportional to the frequency. It is hard to think of an example of a radio wave as quanta (or photons) but the theory holds for all em waves.
