Energy & Electricity in Science : How Is a Photon Produced?


Hi, I’m Steve Jones and I’m going to tell
you how a photon is produced. Now in an atom of course we have a nucleus but above the
nucleus we have electrons. And it was discovered last century, the twentieth century that electrons
can’t have any levels, they can only have specific levels of energy. And we’ve called
these E naught, E one, E two, E three, E four, E four is bigger than E naught. So what happens
is the electrons can go from one energy to another as the material warms up. So the energy
increases or decreases. Now when energy increases, you put energy in to the atoms by heating
or doing something else. But when the electron, say in level two falls down in to E level
one, we can see that there is a difference in energy. And the difference in energy here
would be E two minus E one. So there is a change in energy. That energy is lost. So
where does it go? And the answer is, it goes in to a photon. So a drop in level, say from
E four to E three, the energy associated with that is E four minus E three and this gives
a packet of energy which we call a photon which described as HU. H is a constant called
Plank’s constant after a gentleman called Plank. And U is the frequency. This photon is in
fact electromagnetic, electromagnetic radiation and in fact is or can be light, visible light.
So the electron can actually glow and give out a visible light. It might b X-rays, it
might be infrared, it might be ultraviolet. It can be any of the electromagnetic radiations.
But the photon depends on how big the change is. And the changes can be of all different
energy. So it will give out all different wave lengths and frequencies and all different
types of light. So briefly that is how a photon is produced.

  1. But that's what confuses me so much bout photons.. If it's a particle, how can it have a wavelike motion and go through all objects? how can some bodies reflect the photons and why can some bodies even emit photons then??? (think of a lightbulb)

  2. Thanks for the video! Everyone is trying to understand what exactly a photon is, but no one understands it, not Einstein, not me, no one. But here's what I think. All charged particles are spinning magnetic fields. Therefore the Universe is a magnetic sea. When an electron vibrates, it wiggles the sea, which sends out ripples in the magnetic "fabric" which we see as photons whenever a wave crest passes us. That's my understanding so far.

  3. After watching this video, it tells me that there are 2 types of photons. One is residing in the nucleus of an atom and holding the electrons in orbit and the other is either extracted or inserted into an atom.

  4. Heat isnt a thing, it is simply how fast or slow you atoms are vibrating. His is why it is impossible to get colder than absolute zero, because at absolute zero, the atoms are not vibrating at all. they are still. you can't get slower than still.

  5. photon is just energy, you could say that it is transferred as it exists as potential energy to electromagnetic energy (which is think is classified as kinetic energy)

  6. light is NOT made of protons, photons are created when electrons drop down these levels and potential energy is released in the form of electromagnetic energy

  7. after the change in energy, is the extra energy released out in the form of photons or electrons energize and come out themselves as photons?

  8. Look the new formula for photon's energy on the SALEH THEORY group's youtube chanel: Saleh Theory-com

  9. But how do the electrons stay on their respective levels? . . . And if they're hit with a photon and jump up, why then do they fall back down?
