... frequency of the light so that the amount of slowing of the light so varies. The terminology “light” means all transverse oscillation of an electromagnetic propagation imprinted on flowing U-waves. That includes “light” at lower frequencies than visible light [e.g. infra-red or “heat” and radio wave ...

Physical Optics: Diffraction, Interference, and Polarization of Light
... When light passes through an opening or simply goes by the edge of any obstacle, the wave bends into the region not directly exposed to the wavefront. This phenomena is called diffraction. When the size of the opening or object is large compared to the wavelength of the light, the spreading effect i ...

Waves -- Revision Guide
... Refractive index of a medium depends on the speed of wave in that medium. Selective Polarization of waves (only for transverse waves) A polarizer and an analyser are media that only allow oscillations of a certain direction to pass through. When a unpolarized wave passes through a polarizer, its int ...
