Propagation of Light
Visible light is a narrow part of the electromagnetic spectrum and in a vacuum all electromagnetic radiation travels at the speed of light:
The above number is now accepted as a standard value and the value of the meter is defined to be consistent with it. In a material medium the effective speed of light is slower and is usually stated in terms of the index of refraction of the medium. Light propagation is affected by the phenomena refraction, reflection, diffraction, and interference.
The behavior of light in optical systems will be characterized in terms of its vergence.

t states that light propagates in straight lines in homogenous media.It is one of the fundamental laws of Geometrical Optics which states that: To a first approximation, we can consider the propagation of light disregarding its wave nature and assuming thatlight propagates in straight lines called rays

Linear propagation of light was investigated by using a white-light Michelson interferometer. This method gives the full information on the deformation of broadband optical pulses by the passage through samples in the linear regime. We observed the delay of pulse propagation for cobalt chloride in pyridine, free-induction decay signal for oxazine 1 in methanol, and the increase of peak velocity for nigrosine in water.
