The electromagnet accessory provides a low-friction rotating bearing between the U-shaped core D (P-1000979) and the optical base D (P-1009733) and allows pole pieces and the base plate for the cadmium lamp (P-1021366) to be attached to the U-shaped core D. Pole pieces with PE connectors: Dimensions:                  […]

Mounting plate with six colored light-emitting diodes with different emission wavelengths for determining Planck’s constant h by measuring the cut-off voltage as a function of the frequency of the emitted light. Light-emitting diodes with series resistors mounted on a base plate with a stem. Specifications: Wavelengths: 465 nm, 560 nm, 585 nm, 635 nm, 660 […]

Gas-filled photocell for demonstrating the photoelectric effect and showing that the emission of electrons increases with increasing light intensity. Mounted ready for use on a connector base with electrical wiring and shaft. Specifications: Cathode: Cesium on oxidized silver Cathode area: 2.4 cm² Operating voltage: 50 V, max. 90 V Working resistance: 1 MΩ Dark current: […]

For optical filtering and generation of interference rings in the experiment to demonstrate the normal Zeeman effect. The fixed etalon consists of a substrate with highly reflective, if only partially reflecting, mirror coatings on both sides. The substrate and mirrors form an optical resonator which fulfils the resonance conditions for a specific wavelength of 643.8 […]

Set of easy to handle models of the 14 fundamental lattice types (Bravais lattices), from which Auguste Bravais postulated that practically all naturally occurring crystal lattices can be derived by shifting along the axes. Made of wooden balls in six different colours connected via metal rods. The six colours distinguish the six different systems into which […]
