what is electromagnetic radiation, if not just the energy released from the waves on the electromagnetic spectrum?Is electromagnetic radiation just the energy released by all the waves on the electromagnetic spectrum?
I'd rearrange the question and say:
Electromagnetic radiation IS the electromagnetic waves, the waves carry energy according to their frequency and the range of frequencies is called the electromagnetic spectrum.
We could say the energy is released from the source of the waves, carried away by the waves and transferred into whatever the waves hit.
For example energy is released from nuclear reactions in the Sun, carried through space and finally transferred to the earth.Is electromagnetic radiation just the energy released by all the waves on the electromagnetic spectrum?
Electromagnetic radiation as a phrase needs to be broken down
First we have electro - this relates to an electric field
Then we have magnetic - this relates to a magnetic field and then we have
Radiation, from radiate.
If an electric field is generated in a conductor then a magnetic field surrounds it. The strength of this field depends on the current flow. But a magnetic field also generates another electric field. These beget each other in an expanding composite field - magnetic - electric - magnetic - electric etc
Radiate means having divergent rays - in other words, spraying out from a source in all directions (unless artificially focused) - we get the word radio from this as well
So the electromagnetic spectrum is simply the range of phenomena included in those things which create em radiation. I find it interesting that the spectrum existed before we used it for communications.
Em radiation includes x-rays, microwaves, sunlight, infrared and ultraviolet and radio waves (not in that order) but to answer your question, no it is not the energy released.
However I do not know how the sun produces this radiation unless it is nuclearIs electromagnetic radiation just the energy released by all the waves on the electromagnetic spectrum?
not really, that energy have to be hold to something, called electron, which have a behavior, could be like a particle or wave, but the phenom you find it's not light, electromagnetic radiation instead, so you can measure that radiation with the attraction of that material develops in the environment....
