Researchers at ETH Zurich have developed a method for the production of wavy surfaces with nanometer precision. In the future this method could be used, for instance, to make optical components for ...

Diffraction occurs when a wave encounters an obstruction in its path and will change direction, or wrap around it. In ocean waves, we see this occur when a wave encounters an object like a jetty and ...

French physicist Louis de Broglie proposed in 1924 that particles of matter have wave-like characteristics, with a wavelength (λ) given by the equation λ = h/p, where h is Planck's constant and p is ...
