SW Ultrasonics Set (230 V, 50/60 Hz) U61011-230
Equipment package for demonstrating the basic properties of waves using 40-kHz ultrasonic waves as an example in a space-saving, table-top experiment. Two rod-shaped microphone probes are used to record and analyse oscillations with the help of a standard oscilloscope. An ultrasonic pen can be used to record wave fronts in the plane of the table as lines of equal phase (isophases).
