Ultrasonic diffraction at different single and double slit systems

Product No: P2151515

Principle

A plane ultrasonic wave is subjected to diffraction at single slits of various widths and at various double slits. The intensity of the diffracted and interfering partial waves are automatically recorded using a motordriven, swivel ultrasound detector and a PC.

Tasks

Record the intensity of an ultrasonicwave diffracted by various single slits and double slits as a function of the diffraction angle.
Determine the angular positions of the maximum and minimum values and compare them with the theoretical values.
