INTERFERENCE FILTER. Arrangement for filtering monochromatic beam from incident white light is called interference filter.. When a narrow beam of white light is incident on the filter, it undergoes multiple reflections in the dielectric, it loses a major part of its intensity and finally emerges from the filter as a very narrow band with one or two maxima.. bandgap. energy illuminates a negative electron affinity (NEA) .

Light is an electromagnetic wave. EM waves are transverse. Thus, the electrical field can vibrate in any direction perpendicular to the direction of propagation. Most light sources (candles, incandescent light bulbs etc..) emit light that is unpolarized – the electric field has all possible directions of vibrations.  . R2 = 249k . . . R3 = 2.8k . .
