[QUOTE="GuillemVS, post: 6207865, member: 664453"] When an object is hot its particles are moving faster than when is cold, right? I've searched that particles are electrons and protons, so it means that if we warm a object the electrons will be moving or even accelerating. Every charge accelerated creates Electromagnetic Waves (or light), right? So it means that when a object receives energy, the electrons become excited, and in it's energy release they go down from excitement, and that becomes acceleration of electron that eventually becomes an Electromagnetic Wave, right? So basically we could define a mirror by saying that all the light that comes excites de electrons of the mirror and its dexcitement (is that a word?) creates acceleration of the electron so it's creating the electromagnetic waves back. Now here is my question (apart from the right?s): What defines the wavelength (or frequency) of the electromagnetic wave? Is it the acceleration itself? Or it's a fixed acceleration in which it comes back to dexcited (word?), so then it would be defined by the amount of energy that it has in its excitment? Is every equal wavelength electromagnetic wave at the same level of energy? Another thing: antennas receive electromagnetic waves as electricty, how is this excitement transform into electricity? if that's how it happens? Like I believe that the electrons get excited by the receive of enegy, right?, then how is tranformed into electricity? If the electrons instead of dexciting they just move into another place (because that's electricty, right?, the movement of electrons)? Apart from the theory, antennas receive EM waves as electricity, so: what defines the voltage of the electricity and what EM wave (type of frequency) we receive? I saw that monopoles antennas receive frequencies depending on their length (as dipole but x2) using that 468 feet / x Mhz. I guess that is to fit the wavelength in the antenna? If it's that, what about all the others wavelengths that are smaller and fit in? The only thing that's left of discard is that the amount of volts received define the wavelength depending on your antenna length. More antenna length less volts for the same wavelength, is that true? I mean, I guess if you haven't destroyed all your vains and nails already for how I have destroyed science and physics with my theories, it would be great if you could tell me where I am wrong (I guess it's faster to tell me where I am right xD), I need answers. Thank you in advance for reading. P.S: I don't know what prefix should I use for this, so I put the intermediate one. But I guess this could be too in Basic. [/QUOTE]
