Description

In the experiment P1.6.3.2, the same measuring procedure is carried out, but with the addition of a stroboscope. This is used to determine the excitation frequency f of the motor. It also makes the circular polarization of the waves visible in an impressive manner when the standing string wave is illuminated with light flashes which have a frequency approximating that of the standard wave. The additional determination of the frequency f enables calculation of the phase velocity c of the string waves using the formula

as well as quantitative verification of the relationship
