Question

can an experiment be designed to see the path of electrons and still get an interference pattern? Explain your answer using a thought experiment.

Answer 1

Solution:

a)

No we cant because concept of particle diffraction is come from the quantum mechanics,

So if we observe the path of electron there there will be a uncertainty in the momentum of electron i.e. we will not be able able to observe the diffraction pattern then and if we observe the interference pattern then we will not be able to observe the path.

All this is by Heisenberg uncertainty principle.
