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 ...
In 1967 the Russian physicist Victor Veselago predicted the existence of a material with a negative index of refraction, which he termed “left-handed.” He concluded that in the presence of such a ...
Refractive index (RI) is an important parameter for describing the optical properties of materials and is closely related to sample morphology, density, stress, chemical composition, and other ...
Obtain, evaluate, and communicate information about the properties and applications of waves. SP4.b Develop and use models to describe and calculate characteristics related to the interference and ...
Scientists have demonstrated that negative refraction can be achieved using atomic arrays -- without the need for artificially manufactured metamaterials. Scientists have long sought to control light ...
Light scattering as the basis for size determination of many objects has been explored for a long time. It was Gustav Mie, author of the Mie Scattering Theory, who studied gold nanoparticles in ...
Refraction is explained by looking into a pool and seeing Snell's law in action. We also explore the concepts of total internal reflection and formation of the critical angle. Plan and carry out ...
