... The conditions of maxima and minima in transmitted light are just reverse of the conditions for reflected light. If white light is used, then the film will appear predominately of that colour for which the condition of maximum is satisfied. 114.Newton’s rings : When a planoconvex lens of large radiu ...

Photonic crystals are also known as the electromagnetic wave band gap materials because the electromagnetic wave cannot propagate through the photonic crystal if the incident wavelength is equivalent to the thickness of the unit cell of the crystals. Photonic crystals are the artificial periodic co ...

... Additional UFOFC data in the time and the frequency domain are shown below. Figure S2 shows the overview and the close-up of time-domain waveforms of the generated UFOFC. In the enlarged view over the time range of 10 s, the waveform is periodic with the period of 0.7 s. Within one period, there a ...

Synopsis by Scott Gibb
... I find it remarkable that “the understanding of the polishing process, particularly of glass, remains mired in its great complexity.” This is exciting since it leaves the researcher with an opportunity for exploration. Unlike the figure, the surface finish comes from the process itself and the optic ...

... Darkfield: By using a condenser N.A. greater than the objective N.A., 0th order undiffracted light is rejected at the objective back focal plane, and does not contribute to image formation. Only interference of higher-order diffracted light contributes to image formation. The result is that details ...

Retroreflector
A retroreflector (sometimes called a retroflector or cataphote) is a device or surface that reflects light back to its source with a minimum of scattering. In a retroreflector an electromagnetic wavefront is reflected back along a vector that is parallel to but opposite in direction from the wave's source. The angle of incidence at which the device or surface reflects light in this way is greater than zero, unlike a planar mirror, which does this only if the mirror is exactly perpendicular to the wave front, having a zero angle of incidence.
