 Polarized light waves are light waves in which the vibrations occur in single plane. The process of transforming unpolarized light into po...

X-rays are diffracted by crystals in a manner dependent on the wavelength of the rays and the space lattice of the crystal. Thus X-ray ...

 A diffraction grating is a glass plate having a large number of close parallel equidistant slits mechanically rules on it. The transparent...

As light bends around an obstacle this phenomena can also be observe by passing light through a narrow slit which proves that light ray dev...

The property of bending of light around obstacles and spreading of light waves into the geometrical shadow of an obstacle is called diffrac...
