Diffraction of ultrasonic waves at a pin hole and a circular obstacle
Principle: A plane ultrasonic wave is subjected to diffraction by a pin-hole obstacle and a complementary circular obstacle. The intensity distribution of the diffracted and interfering partial waves are automatically recorded using a motor-driven, swivel detector and a PC.
Tasks:
1. Determine the angular distribution of an ultrasonic wave diffracted by a pin-hole and circular obstacle.
2. Compare the angular positions of the minimum intensities with the theoretical values.
