There are many glorious science-based terms when it comes to surfing. We all talk about swells, of course, the underwater energy that creates a breaking wave. But we'll look at swell angles and ...

Figure 1: Schematics of the degenerate 4WM process on a thin nonlinear film. In this Letter, we experimentally demonstrate nonlinear optical negative refraction in thin metallic nanostructures. We use ...

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 ...

A ray diagram showing refraction at the boundary between air and glass Refraction can cause optical illusions as the light waves appear to come from a different position to their actual source. The ...

To investigate refraction in rectangular blocks and find out how it is different for different substances ...

The objective of the paper is to understand the wave refraction pattern and littoral sediment transport along the SE coast of India. There are areas of erosion and accretion observed along the coastal ...
