Are you sure it couldn't be observed in lab conditions? What is the order of magnitude of the maximum bandwidth that we can got technically (by any means) in microwaves or radiowaves?. Or more generally, in which region of the spectrum is it possible to achieve the higher quotient...

Let me know if I understand what you say, Suppose some effect that can happen in the detector only above some photon energy, like the production of an electron-hole pair. Supposse that the monochromatic wave before the shutter do not have enough frecuency(energy) to produce this effect. With a...

It is known that any non-sinusoidal wave can be regarded as a combination of sinusoidal waves of different frecuencies, with the ‘weight’ of the different frecuencies given by the function called Fourier transform. On the other hand, if we have an electromagnetic wave, we know that it is the...

If we allow the wave to pass only during some short time (i.e, only a pulse) we introduce high frecuencies in the Fourier transform. Anyway, the Fourier transform is modified in some way, while the photon energies shouldn't change.The question is about it.

When we study physics at the faculty we are told that any non-sinusoidal wave can be regarded as a combination of sinusoidal waves of different frecuencies, with the ‘weight’ of the different frecuencies given by the Fourier transform. On the other hand, if we have an electromagnetic wave, we...

Hi, I have posted this doubt in other forums and people don't know the answer. (sorry if my English is not very good!) Let's see: to obtain the operator for the magnetic moment component of a particle, we have to apply a few factors to the spin operator, and one of them, the so-called...

Up! .

Well, I understand this, but I don't see the conection with my doubt. I still think this does not answer the question clearly: What is exactly the reason why Bernoulli does not work in this case?, and Is it possible to predict the velocity increase in a theoretically accurate way?

Currently in Badajoz. I'm afraid not so good, only if you give me some time to think my words!:rolleyes: I am not sure if I understand, do you mean that Bernoulli don't hold with a hose?. In my hose the flow is smooth. Turbunence? I don't know. If I understand to ezskater and russ_watters...

Hi from Spain, I hope somebody could answer the following doubt, In the typical problem of the water deposit open on the top and with a hole that allow the water to escape through, the theoretical velocity of water when it leaves the deposit and enter in the air does not depend on the size...
