Explains the concept of light traveling in straight lines and demonstrates this through various experiments. It shows how light can be observed through holes in cards, how it behaves in a lightproof ...

I test a series of light experiments to explore reflection, refraction, and optical illusions, demonstrating how light behaves in surprising and educational ways. Elon Musk predicts future without ...

The famous double-slit experiment, which demonstrated that light is both a wave and a particle, has been performed using “slits in time”. The techniques involved present a new way to manipulate light ...
