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 ...

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. ‘I’m sorry’: Embattled Albo’s apology ...
