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 ...

When people look into a mirror, they see an image of themselves behind the glass. That image results from light rays encountering the shiny surface and bouncing back, or reflecting, providing a ...

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 ...
