A glass prism is a transparent object having two triangular ends and three rectangular sides. The refraction of light in glass prism is different from a glass slab. This is because in glass prism, the ...

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 ...

Light is refracted when it enters a material like water or glass. Depending on the density of the material, light will reduce in speed as it travels through, causing it to change direction. Ray ...

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 ...

For as long as physicists have known about gamma rays, they have believed that it would be impossible to create a practical lens that could focus them like light. Now, however, a team of physicists in ...

There has been a surprise discovery of ‘significant’ refraction of gamma rays which opens the door to nuclear photonics and the use of high energetic light beams to investigate the atomic nucleus.
