If the surface is clean and reflective enough, rainbow colored bands of interference fringes will form when the test piece is illuminated with white light.
32.
These interference fringes determine the flatness of the work piece, relative to the optical flat, to within a fraction of the wavelength of the light.
33.
As heavier objects shifts the position of the atoms nearby, displacement of the atoms can be measured by detecting a shift in the interference fringes.
34.
A laser beam generally approximates much more closely to a monochromatic source, and it is much more straightforward to generate interference fringes using a laser.
35.
When a beam of atoms pass through a diffraction grating, due the inherent wave nature of atoms, they split and form interference fringes on the screen.
36.
A small angle is introduced between the interfering waves so that the period of resulting system of interference fringes significantly exceeds the size of the images.
37.
These are not interference fringes, and are sometimes referred to as'correlation'fringes since they map out areas of the speckle pattern which are more or less correlated.
38.
This beat frequency can be thought of as an interference pattern in time . ( The more familiar interference fringes of interferometry are a spatial pattern ).
39.
The conditions for the waves to be antiphased or in-phased ( holographic subtraction or addition ) are automatically created within a dark and bright interference fringes, correspondingly.
40.
In Young's experiment, the individual slits display a diffraction pattern on top of which is overlaid interference fringes from the two slits ( Fig . 2 ).
