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 ...

Perhaps one of the most famous experiments in physics has been giving us the wrong message all these years. For nearly two ...

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 ...

Does the universe notice that we're paying attention to a quantum experiment? The answer goes against everything we thought we knew.

Quantum interference, in particular, plays a key role. It occurs when different pathways that a molecule can take overlap, resulting in specific patterns of interaction: some pathways amplify each ...
