In this activity, pupils will learn about refraction and reflection, and how they’re different. You only need simple bits of ...

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.

I test a series of light experiments to explore reflection, refraction, and optical illusions, demonstrating how light behaves in surprising and educational ways. New bombshell as ex-minister's aide ...
