The double-slit experiment is one of the most famous experiments in physics and definitely one of the weirdest. It demonstrates that matter and energy (such as light) can exhibit both wave and ...

Interference can arise with one source of waves where the waves travel different distances before meeting. The difference in the distance travelled (the path difference) must be a full number of ...
