The double slit experiment and Superposition
The double slit experiment and Superposition
The double slit experiment takes a special position in physics in that it is used as a "crucial experiment" both by classical and quantum Physics. While the first, classical physics, shows an understandable historical preference for light, quantum Physicists, also very understandably, very often use electrons to get their point across.
When electrons or photons are ejected in the direction of the two slits, some strange things happen:
1) w
The idea that observation changes the object or phenomenon observed is a central tenet of the Copenhagen interpretation of quantum mechanics. I will not attempt to discuss the meaning of this principle for the whole domain of the theory, but will limit myself to the case I have presented in this thread.
Double slit experiments show interference patterns when one or two slits are open, but those same patterns seem to disappear when the experimenter tries to determine through which slit the part
