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. GOP lawmakers push for charges ...

Light is often thought to reflect from a flat surface at the same angle at which it is incident. Nature Photonics spoke to Han Woerdman about the observation of angular deviations of reflected beams.
