Description

In the experiment P1.7.5.2, two identical ultrasonic transducers are operated by a single generator. These transducers generate two coherent ultrasonic beams which interfere with each other. The interference pattern corresponds to the diffraction of flat waves at a double slit when the two transducers are operated in phase. The measured intensity is thus greatest at the diffraction angles α where
