The first experimental verification of Snell’s law for spin waves has been carried out by an international team of researchers. By imaging the incident, refracted and reflected waves at interfaces in ...

Refraction is described and students learn to draw diagrams of refracted waves. Refraction is described and students learn to draw diagrams of refracted waves. They also learn to describe diffraction ...

The interface between two facets of an artificial material known as a “Weyl phononic crystal” can not only negatively refract an airborne sound wave, it does so without reflecting it at all. This ...

Refraction close refractionProcess by which a wave changes speed and sometimes direction upon entering a denser or less dense medium, eg a light ray changes direction when refracted by a lens. of ...

Sara and Beca are at home using the computer when they come into difficulties trying to ‘surf the web’. Ada misinterprets the girls’ discussion and starts to explain waves through Sara’s tablet ...

Straight wave reflection from straight barriers, 80-231, approx 3 minutes Single straight pulses are reflected from a straight barrier placed parallel to the wave front, then at 35, 45 and 55 degrees.
