Description

The aim of the experiment P1.7.4.1 is to confirm the law of reflection “angle of incidence = angle of reflection” for ultrasonic waves. In this setup, an ultrasonic transducer as a point-type source is set up in the focal point of a concave reflector, so that flat ultrasonic waves are generated. The flat wave strikes a plane surface at an angle of incidence α and is reflected there. The reflected intensity is measured at different angles using a second transducer. The direction of the maximum reflected intensity is defined as the angle of reflection β.
