In the years since Pendry’s work, the pursuit of negative refraction has led to developments in optics, acoustics, plasmonics (the study of how light interacts with electrons in metals) and even ...

Refraction is the bending of light rays. Normally, light travels in a straight line, and changes direction and speed when it passes from one transparent medium to another, such as from air into glass.

In my previous Photography Snapshot, I discussed the importance of light and how it bounces to create images. In this Snapshot we will discuss the difference between reflection and refraction, how ...

Reflection and refraction occur whenever light encounters a material at an angle, because one side of the beam is able to race ahead of the other. As a result, the wavefront changes direction.
