Physicists have finally turned a long standing thought experiment into a laboratory reality, showing that electromagnetic waves can be reflected in time as cleanly as light bounces off a mirror in ...

A new class of optical thin-film materials enables the refractive index to be tuned to extremely low values. E Fred Schubert and colleagues believe that this capability could have important ...

Wave Optics Class 12 MCQ Questions: In this chapter, we will be discussing the wave model of light which in 1678, the Dutch physicist Christiaan Huygens had put forward. The wave model could ...

In “What is Light?”, we described light as both a wave and a particle under the conditions of the wave-particle duality. In the previous posts, we have mostly modeled light as a ray when discussing ...

The basics of fiber optic cables and bundles and how they can be used to collect and direct light are discussed in ‘An Introduction to a Spectrometer: Fiber Optic Bundles’. This article will discuss ...
