Classical physics theories suggest that when two or more electromagnetic waves interfere destructively (i.e., with their electric fields canceling each other out), they cannot interact with matter. In ...

When two or more light waves interact with one another, they result in the formation of different interference patterns. British physicist Thomas Young first demonstrated and explained these patterns ...

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 ...
