The film explores the dual nature of light, demonstrating its behavior as both a wave and a particle through an experiment involving a double slit. It shows how light creates an interference ...

In many ways, this theory had been previewed by atomists of Classical Antiquity – such as Democritus and Lucretius – both of whom viewed light as a unit of matter given off by the sun.

According to the particle theory of light, the speed should be faster when light passes from one substance to another that is denser, as is the case when light moves from air to water.

While scientists know light can act like both a wave and a particle, they've never before seen it behaving like both simultaneously. Now a new experiment has shown light's wave-particle duality at ...
