lets say a structure has 3 resonance structures, i konw that the atoms don't move, but i read somewhere that the electrons do...hmmm and that the resonance hybrid is most stable ofthe resonance forms?? I am confused, what exactly is resonance? in actuallity, isn't there no resonance , just...

Hello, consider a dihydrogen molecule in a powerful magnetic field and an x-ray that is hitting this molecule. Many things could happen in this case I think: compton effect, ionisation, electrons changing orbitals, nuclear magnetic spin state changing... My question is: can I be certain...

"An electric motor of mass 100 kg is supported by vertical springs which compress by 1 mm when the motor is installed. If the motor's armature is not properly balanced, for what revolutions/minute would a resonance occur?" I set my frame of reference at the end of the spring. Therefore, F =...

I've been reading about nuclear magnetic resonance, and one aspect is bothering me. (I haven't studied quantum physics yet.) Quantum mechanically, the proton has only 2 energy states: spin +1/2 spin and spin -1/2. In NMR, a pulse of electromagnetism is applied to alter the orientation of the...

A tuning fork is set into vibration above a vertica oepn tube filled with water. The water level is allowed to drop slowly. As it does, the air in the tube above the water level is heard to resonate with the tuning fork when the distance from the tube opening to the water level is 0.125 m and...

You have 2 pendulums attached to the same piece of horizontal string. One pendulum has a large mass, the other is small. They are both of the same length. The large pendulum is released from an amplitude and so the small pendulum resonates. The rate of exponential decay of the large...

I have been trying to figure out the acoustical resonant frequency of objects. I think their are engineering formulas that could be used. For example if you have a 1x1x1inch block square of iron, at what acousticaly resonant frequency would it be tuned to? I imagine the shape would have...

I am multi-tasking here, but the questions are all linked. It is interesting to note that the range of peak Schumann Resonance frequencies [the ionosphere] land right in the range of the peak amplitude EEG frequencies. I first noticed this by chance some time ago. I then noticed a related...

Does increase in velocity and/or mass increase the effect on an atom's resonance? I was thinking maybe the faster an atom travels in one direction the slower the atom would vibrate. Any thoughts on this matter?
