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 ...

Refraction is the change in direction of light when it passes from one medium to another. The working of a lens is based on the refraction of light when they pass through it. Lens is a transparent ...

Well, OK, not exactly. A beam of light could pass through air all day long (as long as you have a layer of air 26 billion kilometers long) and not deviate a whit. But if the density of that air ...

For the first time, scientists have demonstrated that negative refraction can be achieved using atomic arrays - without the need for artificially manufactured metamaterials. Scientists have long ...

The idea of creating negative refraction by exploiting the collective electron acceleration (inertia) effect, or kinetic inductance, was theoretically proposed for specific arrangements of ...

An unusual optical phenomenon explains why the Titanic struck an iceberg and received no assistance from a nearby ship, according to new research by British historian Tim Maltin. Atmospheric ...
