Webtwo beams of light that are polarized at right angles to each other but which are not sheared. The phase relationship of the two beams can be adjusted by shifting the position of the final prism across the two beams (Figure. 11.3). For example, moving the right prism down would slow the O ray more than the E ray. http://electron9.phys.utk.edu/optics421/modules/m5/Interferometers.htm

The … WebInterference occurs when two light beams have the same frequency, and the phase difference is a constant . ... Figure 8a demonstrates the interference fringes of the …

WebThe path lengths that the two beams follow to the receiver will change in length as the receiver moves. When the two path lengths differ by a whole number of wavelengths, constructive interference (high intens ity) will occur. When the two path lengths differ by an odd number of ½ wavelengths, destructive interference (low intensity) will occur. WebIn areas where the waves meet totally out of step, they will subtract from each other owning to destructive interference, and a dark area will appear in that portion of the screen. The resulting patterns on the screen, a product of interference between the two diffracted beams of laser light, are often referred to as interference fringes.
