a first subtle question for those physicist,
What is the time that the electron need to jump from one energy state to the next energy state? [a professor’s answer]
I am a EECS person, But I know the importance of materials structures for my circuits and system to perform. I know Carbon network is the future, but in order to harness it’s power I have to understand how the network or bond form between atoms (carbon for example).
I started with quantum mechanics, first thing I learned is the E=hv, it’s fine, discrete energy is not a problem for me to accept, but the concept of energy is related to frequency, I took 1 hour to figure it out, the real reason is classical mechanic ‘think’ the energy is the area under the signal in the amplitude-time plane, which is not actually true for EM waves, for EM waves, the energy is the area under the spiral of the EM vector in E-M-T 3D space. then the frequency does contribute to the area, therefore related to the energy.
the second concept than is the discrete frequency/energy for those photons, after a bit of thought, I know it’s a consequence of standing waves, but what is from of the standing wave, if you think the very first question I asked, electron jump/drop from one energy state to another state, how long does it take? if the answer is 0, then the frequency will be infinite and there will be not way we can see it either by eye or instrument! if the time is 1/f, then the length of the gap will tell us the time, but note, for H, 3->2 transistion give a 656.3 nm gap!! a transistor in today’s semiconductor process only has a gap of 28nm!
so how about look at it from a different perspective, a standing wave in the energy band ring, 2*pi*radius=656.3nm, which give the radius 104.45nm, still a bit too big, how about 4/3*pi*(radius)^3, which give 5.39nm for 3->2 gap of H, given the fact that H=H(base band) bond is 31 +-5pm, 3->2 band should be much bigger to generate the 656.3nm light, which is the lowest for hydrogen.
I will make more figure for the explanation, but now, let’s think about the consequence of this electron model for atom. first, electron don’t really have those rigid energy bands now, instead, it’s like a spherical standing wave! imagine a water sphere in space, the surface standing wave is what I am talking about.
what about double split experiment, think electron as a cloud or loosely coupled network like water, you can get the right result.
so what is electron then, and why it can be used to from bonds between atoms, well, I would like to imagine two water drops positively charged and surround by a layer of oil and another layer of negatively charged water, both floating in space, and they should form bond if the amount of charge for each layer is right.
a last question, is speed of light really constant? I would say electron’s standing wave motion is the key, currently, c=wavelength * frequency, if the wave length is the radius of the sphere, then the outer layer will have slower frequency, and inner layer will have higher frequency, so the product for c is a constant.
in our world, matter seems to either reflex or slow down light. and the maximum speed is when there is no atom in it’s way.
but what if the atom is a anti-matter? will these pattern reverse, say, speed it up? you can also check the article below
