quantum mechanics - Altering Young's double slit experiment due to observation


The interference pattern on the screen is altered due to our observation, but how could this happen, as we have been watching it since we started the experiment? Is there any other meaning of 'observation' in this experiment?



Answer



It depends on what, exactly, is observed. In the standard version of the experiment, only the position of the electrons as they hit the screen is detected. In this case there are interference patterns. It's only when an additional observation is made, the passage of the electrons through one or the other slit, that the interference patterns disappear.
