"CORNELSEN EXPERIMENTA"

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: CORNELSEN EXPERIMENTA

Bare wire in a roll, on a plastic former.

Supplier: CORNELSEN EXPERIMENTA

Shows that the bottom pressure in a liquid depends only on the height and not the shape of the container. The fluid pressure is transferred via a rubber diaphragm to an adjustable hand. Comes with four containers of different shapes. Dimensions.

Supplier: CORNELSEN EXPERIMENTA

Intended for use on overhead projectors for demonstration of function and principle for different types of motors. Made of strong, transparent plastic. Equipped with suction feet.

Supplier: CORNELSEN EXPERIMENTA

Bicycle dynamo with transparent housing. Consists of magnetic anchor and coil mounted on base with belt drive. Equipped with connections for 4 mm banana plug and light bulb 3.5 V/0.2 A.

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: 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: CORNELSEN EXPERIMENTA

Piston air pump on a stable plastic base with rubber feet, non-return valve with a bleed screw, pump plate and vaccumm connection to the centre of the plate.

Supplier: CORNELSEN EXPERIMENTA

To display ultraviolet radiation. Half of the plate is coated with a fluorescent substance that emits light during UV radiation.

Supplier: CORNELSEN EXPERIMENTA

Consists of a plastic cylinder placed on an insulating rod between two tip electrodes. When connecting a high-voltage source, a charge transport is obtained which causes the cylinder to rotate.

Supplier: CORNELSEN EXPERIMENTA

Used to detect electric charge. Also suitable for use with belt generator and Faraday's cage. Equipped with connection for 4 mm banana plug.

Supplier: CORNELSEN EXPERIMENTA

For charging attempts. About 50 pcs in a box.

Supplier: CORNELSEN EXPERIMENTA

Used for electrostatic experiments.

Supplier: CORNELSEN EXPERIMENTA

For storage of electric charge. Consists of a glass cylinder with metal foil and a conductor ball on a rod.

Supplier: CORNELSEN EXPERIMENTA

Metal plate with four rows of holes at different distances. By simultaneously setting the disc in rotation and blowing with a blowpipe, a major chord is obtained. The disc is used together with a hand-driven rotary apparatus or an electric motor. Disc Ø: 200 mm.

Supplier: CORNELSEN EXPERIMENTA

Consists of a ball with check valve, vent valve and suspension hook. For use in conjunction with an electronic scale (0,001 g).
