Optical Receiver Principle Test Experiment

In modern physics, the double-slit experiment demonstrates that light and matter can exhibit behavior associated with both classical particles and classical waves. This type of experiment was first described by Thomas Young in 1801 when making his case for the wave behavior of visible light.
