An acoustic double-slit system (of slit separation d and slit width a) is driven by two
Chapter 36, Problem 113(choose chapter or problem)
An acoustic double-slit system (of slit separation d and slit width a) is driven by two loudspeakers as shown in Fig. 36-51. By use of a variable delay line, the phase of one of the speakers may be varied relative to the other speaker. Describe in detail what changes occur in the double-slit diffraction pattern at large distances as the phase difference between the speakers is varied from zero to 2p. Take both interference and diffraction effects into account. AudiosignalgeneratorVariabledelaylineSpeakers Figure 36-51 113.
