Lignt being a wave must express the phenomenon of bending at the edges. But this is not easily observed. This is mainly because of the shorter wavelength of light. Hence we come to the conclusion that light never bends and always travel in straight lines. This is what we call rectilinear propagation of light. This was successfully explained by Young and Fresnel with the concept of half period zones. Also light waves considered as transverse in nature.
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. By Fourier analysis of the interferograms, complex optical constants of the samples were also obtained.
