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 ...

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 ...

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 ...

Refraction close refractionProcess by which a wave changes speed and sometimes direction upon entering a denser or less dense medium, eg a light ray changes direction when refracted by a lens. of ...

Figure 1: Analytical study of one-dimensional chains of resonant point scatterers. Starting from this unit cell that creates the single negative property, we build two new configurations just by ...

To investigate the reflection of light by different types of surface, and the refraction of light by different substances. Remove the block. Join the crosses to show the paths of the light rays ...

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 ...

For today's column, I'm building on previous discussions of botanical photography and incorporating new techniques that are still attainable with common household objects. Last month, I had intended ...

Light energy travels in straight lines and in waves. Light energy travels in straight lines and in waves. When light strikes a plane or a flat surface, it reflects in a manner that is predictable. For ...
