Question

Suppose a beginning physics student asks you if it’s possible for a particle to be at two different places at the same instant in time. Use the Double-Slit Experiment to answer the student’s question. Details would be really helpful

Answer 1

As our technology gets advanced as time passes, we are in the position to show double slit experiment using only one particle at a time.

Suppose in double slit experiment if we take one particle and pass it through one slit with one slit closed then there is no interference pattern observed and if we repeat this for another slit result will be the same i.e there is no interference pattern.

Now if we open both slits and take one particle at a time we see that there is interference pattern observed at the screen.

This is only possible only when one particle at a time be in two different places.
