Physics Educational Materials

Supplier: CORNELSEN EXPERIMENTA

For experiments with absorption of heat radiation. Consists of a black and a white E-flask and two thermometers (0 to 50 °C).

Supplier: PHYWE

Ice cream sphere filled with noble gas of low pressure. The tube's two cylindrical necks are protected by plastic sleeves and are designed to fit in Helmholtz coils 765-1207. The tube is used to show how an electron beam is deflected in a magnetic field. If the tube is in a homogeneous magnetic field with sufficient strength, the electron beam becomes circular. The tube is equipped with an internal measuring scale with fluorescent markings at distances of 4, 6, 8 and 10 cm (2r) from the cathode. The tube is well suited for determining the charge-mass ratio of the electron with great accuracy.

Supplier: GR NNA PLASTEMBALLAGE AB

Used to show the effect of air resistance in free fall. An air pump or water suction is used to evacuate the air in the pipe. Supplied with: 1 glass tube, 2 rubber plugs, one of which with a crane tube. 3 test specimens of resp. down, plastic and lead.

Supplier: PHYWE

TESS OE3 contains 19 components. With TESS OE3 as a complement to TESS OE1 and OE2, another 30 experiments can be performed in the field of wave optics. Delivered in a plywood box.

Supplier: GR NNA PLASTEMBALLAGE AB

Trolley, 100 g, of lacquered sheet metal with nylon wheels. Equipped with hook and hole for mounting weights.

Supplier: PHYWE

Precision capacitor for electrostatic tests e.g. examination of the relationship between charge, voltage and capacitance. Measurement of the dielectric constant and the electrostatic induction constant. The permanently mounted plate is well insulated while the movable plate is mounted directly in the stand. The distance between the capacitor plates can be adjusted with an accuracy of 0.1 mm. Distance between plates 0 to 70 mm.

Supplier: CORNELSEN EXPERIMENTA

72 series-connected semiconductor elements, mounted between two ceramic plates which in turn are attached to heat-conducting metal. If the metals are exposed to different temperatures, a voltage arises, sufficient to drive, for example, a slightly rotating motor. The thermogenerator can also be run in the other direction, ie. a voltage is connected and a temperature difference is obtained across the metal legs.

Supplier: 3B Scientific

Highly evacuated electron tube for determining the wavelength of electrons as a function of the anode voltage from the radii of the diffraction rings and the distance between the lattice planes of graphite (Debye-Scherrer-diffraction) and rendered visible on a fluorescent screen. Also intended for determining the wavelengths of monochromatic radiation at different anode voltages from the radii of the diffraction rings and the lattice plane spacing of graphite, as well as confirming de Broglie’s hypothesis.

Educational Materials, Mechanics, Application: Physics, Pendulum ball, steel, 60 mm

Supplier: 3B Scientific

Suitable as a source of intense, high frequency sound, for example, for producing stationary sound waves in Kundt's tube.

Supplier: CORNELSEN EXPERIMENTA

For acoustic detection of standing sound waves and for determining the wavelength of the sound source and then the speed of sound in air (Velocity=frequency×wavelength). The system is filled with water and a sound source (tuning fork) is held to the open tube end. By varying the height of the reservoir and the height of the liquid in the tube students can determine the wavelength using audible effects associated with standing waves.

Supplier: PHYWE

Coil springs made of spring steel. With stirrups at both ends. Suitable for Hook's team and swing attempts.

Supplier: 3B Scientific

Transmission grating for spectroscopic examinations and for experiments on diffraction and interference. Suitable to resolve the sodium D lines.

Supplier: CORNELSEN EXPERIMENTA

The kit contains components for basic laboratory work with solar cells. The components are simply designed and the students quickly build their experimental setups. With the rate, e.g. the following are studied.
