Are radio waves (especially ELF waves) faster than light waves or the speed of light?
shorter path or shorter wavelength and therefore faster?

I'd like to get a heated exhaust fan with a grow controller, but compatibility isn't mentioned. Since I use Sanlight lamps, I don't know what they're compatible with. what would you recommend to me? would like to monitor and control fans, light, exhaust air, etc. via controller
Can an E14 oven bulb also be used in a refrigerator?
The candle-shaped light bulb in the refrigerator has given up the ghost. I have a very small E14 oven bulb at home. I just screwed it in, but it got quite uncomfortably warm while I was screwing it in, i.e., while it was still lit. I quickly unscrewed it again just to be safe. Was…
Why does the mass of black holes decrease?
ByParres
Hello, I have a question: Black holes can lose mass through Hawking radiation. This happens because, according to quantum mechanics, particle and antiparticle pairs form and do not annihilate each other. Instead, the particle with negative energy falls into the black light and the particle with positive energy escapes the black hole. My question is:…
Can anyone help with physics?
Hello. Can anyone help me with the following task? I've managed to calculate the number of turns. But how do I calculate the thickness (I think that's the diameter) and the length? I would be happy to receive answers. Best regards
Hello Kleosa,
In principle, radio waves are nothing but light, only the frequency range is different than visible light.
No, the wavelength of radio waves is much Other. In addition, the shaft line not the path of such a wave (see FIG. 1); this is straight.
Figure 1: The wave line of the wave is not the path of the wave through the space, but represents the electric field strength E› and the magnetic flux density B›.
What can happen, of course, is that waves of visible light are “decelerated” considerably more by matter than, for example, infrared light, micro waves or radio waves.
No radio waves move in the vaccuum at the same speed as light, essentially they are also only light with greater wavelength.
In materials there are of course different propagation speeds which depend on the material, the spatial geometry etc.
Ave!
No.
The propagation speed of an electromagnetic wave is always exact speed of light (in the respective medium)
The wavelength has absolutely nothing to do with it.
With this analogy, the light would otherwise be different quickly, since the light itself also has different wavelengths.
yes blue is slower than red light…
No, it’s only in media.
Radio waves move at speed of light, just like other electromagnetic waves
No, they don’t spread out faster…
No.
