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.

THE experimental and theoretical investigations of the last twenty years have lent a new interest to what, I venture to think, is one of the most fascinating branches of physical optics, namely, the ...

I test a series of light experiments to explore reflection, refraction, and optical illusions, demonstrating how light behaves in surprising and educational ways. ‘I’m sorry’: Embattled Albo’s apology ...
