Wave Interference
Mike Moloney
Rose - Hulman Institute of Technology
Use your computer to learn about the importance of phasors.
Move your mouse and instantaneously view the resulting differences in the phasors and interference. This live
phasor addition can be compared to both intensity plots (gray scale and line) and to the numerical value of the
relative intensity.
Display how phasors are used to obtain various intensity patterns. Sources in a line are used to illustrate the behavior of single slits, gratings, double slits, and the circular aperture. The wave amplitude is independent of the distance from the source, calculates the exact path differences between source points to the field point and the resultant amplitude, and displays the pattern.
Wave Interference can be used by individuals or part of a full-class demonstration. A tutorial section on wave motion and phasors, adding two waves, and path difference effects is included. Additional problems and exercises with solutions enliven classroom use. Several problems make the connection between grating behavior and the far field patterns of antenna arrays, thus emphasing that both transmitting and receiving arrays have the same directional properties. This focus is traditionally missing from most textbooks. 50 pp.
