Polarization of light II
... This fact can be used to get a polarised beam of light from an unpolarised beam. An unpolarised beam is made to incident at an interface at Brewster angle. The reflected beam will contain the s component only. In this experiment , you will study the variation of intensity as a function of angle of ...

Historical burdens on physics 54 Coherence of waves
... that does not mean that coherence or incoherence is a property of the source. 2. Coherence is a local property of the light. That means that a given light distribution can be more coherent at one place than at another. So the spacial coherence of the light that is emitted by a star is minimum at the ...

Interferometry
Interferometry is a family of techniques in which waves, usually electromagnetic, are superimposed in order to extract information about the waves. Interferometry is an important investigative technique in the fields of astronomy, fiber optics, engineering metrology, optical metrology, oceanography, seismology, spectroscopy (and its applications to chemistry), quantum mechanics, nuclear and particle physics, plasma physics, remote sensing, biomolecular interactions, surface profiling, microfluidics, mechanical stress/strain measurement, and velocimetry.Interferometers are widely used in science and industry for the measurement of small displacements, refractive index changes and surface irregularities. In analytical science, interferometers are used in continuous wave Fourier transform spectroscopy to analyze light containing features of absorption or emission associated with a substance or mixture. An astronomical interferometer consists of two or more separate telescopes that combine their signals, offering a resolution equivalent to that of a telescope of diameter equal to the largest separation between its individual elements.
