Unless you specify what you are talking more precisely, it does not seem very likely that this makes sense at all. At least it does not to me. What do you mean by turn off ? If you have an optical lens, you can't turn it off. If you have a magnetic field, most probably it's created from a current you can switch off. If you have a semiconductor photodetector, it does not matter whether voltage is off or on when it comes to collapsing a photon's wave function.Sabradin said:
As many as one can think of I guess. How many materials can you build out of Mendeleev table ? Do you count measuring a photon with water different from measuring it with vapor or from ice ?Sabradin said:
Is there a voltage applied to a photographic plate ?Sabradin said:
Well, maybe I have seemed overreacting : I answer while it compiles, and there is nothing worse than a shared library which should load but does notSabradin said:
Sorry if I seemed rude.
Formulated this way, the question becomes trickier. If there is any interaction whatsoever between the photon and the device, energy needs to be conserved. Ultimately, your photon hits an atom, maybe inside a molecule, but this atom will certainly reach an unstable excited state and indeed, emit something. However, if this emitted "thing" finally turns into phonons in a crystal, you have merely heated your device. Does it count as "emitting" ? You could say, yes, the heated device will emit (IR) radiation, that is a very long way to scatter a photon !
Us seeing the aftermath. The photon carries an energy which has not been stored in a single atom after the photon has been absorbed. The atom would wait for you to check whether it has been excited ? At the very least you have one single Compton scattering.WarPhalange said:

Yes, a measuring device can be turned off while measuring a wave. Turning off the device will stop the measurement and the data will no longer be recorded.
Yes, turning off a measuring device can affect the accuracy of the measurement. This is because the device may need to be recalibrated or the data collected before turning off the device may be incomplete.
It is unlikely that turning off a measuring device while measuring a wave will cause any damage to the device. However, it is important to follow the manufacturer's instructions for proper use and care of the device.
It depends on the specific device and measurement being taken. In some cases, it may be necessary to turn off the device to prevent damage or to get an accurate measurement. In other cases, it may be better to let the device continue measuring in order to collect more data.
The best way to turn off a measuring device while measuring a wave is to follow the instructions provided by the manufacturer. In general, it is important to make sure the device is in a stable position and that any data has been saved before turning off the device.
