Photocell unit for mounting on stand
Photocell unit for mounting on standFor pendulum period measurements, air track timing, measuring period of rotation etc. It connects to electronic counters of type 200250 or 200260 using the supplied cable with DIN plug. Made from impact-resistant plastic with threads for vertical and horizontal mounting using the supplied Ø 10 mm support post.
Photodetector
PhotodetectorThe photodetector can be used to demonstrate communication by laser light, fibre optic communication, plotting of interference patterns etc.
Physical pendulum/Bessel pendulum
Physical pendulum/Bessel pendulumThe physical pendulum is used to study moments of inertia and the motion of rigid bodies. The centre of gravity, pivot point and moment of inertia can be varied in innumerable ways. For calculation, Steiner’s theorem is useful, as well as a number of formulae for moments of inertia of the pendulum’s different components.
