  • An Introduction to Light Amplification
    Article - 4 Aug 2014
    Light amplification is a process of intensifying the amplitude of an electromagnetic light wave. This process is generally classified into three major categories: laser, parametric and scattering.
  • Refraction and the Refractive Index
    Article - 30 Aug 2007
    When light passes from one medium to another of different density, its path of travel is bent. This phenomenon is known as refraction.
