Unformatted text preview: produces a wave having some particular orientation of the electric field vector E, corresponding to the direction of atomic vibration. The direction of polarization of each individual wave is defined to be the direction in which the electric field is vibrating .In a polarizer the filter has a layer of Polaroid between two glass plates. In an ideal polarizer, all light with E parallel to the transmission axis is transmitted, and all light with E perpendicular to the transmission axis is absorbed. Neutral Filter A neutral density filter can be colourless.An ideal; neutral density filter reduces the intensity of wavelength by allowing the photographer to change aperture,exposure,or time of subject in different atmospheric condition....
