Ultrasonic diffraction by a straight edge
Principle: An ultrasonic wave hits a straight edge which limits the wave field to one side. According to Huygens' principle, the edge is a point source for secondary waves, and these penetrate also into the shaded area of the edge. In the permeable area, secondary waves interfere with the primary waves, so that a succession of maxima and minima of the alternating sound pressure are created transverse to the edge.
Tasks:
1. Determine the intensity distribution of an ultrasonic wave diffracted at a straight edge as a function of the transverse distance from the edge.
2. Compare the positions of the maxima and minima found in the experiment to those theoretically expected.
3. Repeat the measurement of the intensity distribution of the ultrasonic wave without the straight edge.
