If the light rays are travelling from one medium to another they change their direction at the boundary between two mediums. When the light rays either bend or change their direction while passing ...

The first law of refraction states that the incident rays, refracted rays, and the normal to the interface at the point of incidence, all lie in the same plane. The ratio of the sine of the angle of ...

A light ray is traveling in a transparent material of refractive index 1.51 at an angle of incidence of 38 degrees and approaches a second material of refractive index 1.46. Solve for (a) the angle of ...

Welcome to science world! Today, we're going to have a look at a particular type of wave - a light wave. Who knew so many different things travelled in waves? A light wave travels faster than anything ...

Figure 1: Diagram and SEM image of fabricated fishnet structure. Here we experimentally demonstrate the first 3D optical NIM by directly measuring the angle of refraction from a prism made of cascaded ...

A fundamental building block for nanophotonics is the ability to achieve negative refraction of polaritons, because this could enable the demonstration of many unique nanoscale applications such as ...
