8113 Coupled pendulum

The apparatus of coupled pendulums consists of two pendulums paired through a coil spring slightly stretched out. The spring allows the energy to be transfered between the two pendulums so it is possible to study the phenomena of resonance and beats. The apparatus of coupled pendulum can be used as optional equipment of the apparatus for the study of harmonic oscillations (code 8111) or with the stand (code 0209), sold separately.
