Supplier: PHYWE

Glass tube used to demonstrate standing waves and acoustical forces. When used in conjunction with a sound source (single frequency), plunger to alter the effective length of the tube and cork dust or talcum powder, the tube can be made to resonate and the powder will aggregate at nodes in the tube. Calculation of the wavelength and speed of sound can be calculated from the measurement of these nodes.

With a few simple steps, the ballistic pendulum is quickly rebuilt into a throwing device with a variable/variable firing angle. The ballistic pendulum, a common method for determining the speed of a pistol bullet, is to push them into a sandbag. With the ballistic pendulum, a harmless variant of this experiment can be performed in the classroom.

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: PHYWE

Apparatus for detecting that the pressure at the bottom of a container does not depend on its design, but only on the liquid level. For quantitative determination of the hydrostatic pressure and examination of the linear relationship between pressure and liquid level. The liquid pressure at the bottom of the various vessels deforms a highly elastic rubber membrane whose movement is transmitted to a centimeter-graded needle. The deviation can be compensated with weights. The mass and distance of the weight from the pivot point make it possible to quantitatively determine the pressure change. A second pointer can be mounted vertically to visualize fluid level.

Supplier: PHYWE

Two identical coils with a diameter of 400 mm (2R), 154 turns of winding each and mounted on separate sockets with connection contacts. Distance between coils 200 mm (R). The coils are held together by three detachable rails. Two of these have brackets for wire beam tubes 765-1206. The coils are used, for example, to provide a homogeneous magnetic field in the wire beam tube. Suitable voltage: 7 V DC (well smoothed) if the coils are connected in parallel and 14 V DC for series connection.

Supplier: 3B Scientific

Spoked wheel with weighted rim for demonstrating conservation of angular momentum. Simple to use due to small wheel radius and ease of suspension. Teachers and students can feel the conservation of angular momentum as they hold the spinning wheel while sitting in a rotating chair or standing on a rotating platform. You can also create the effect of precession by spinning the bicycle wheel and hanging it from a string.

Supplier: PHYWE

Equipment for demonstration of the quantum properties of the electric charge, as well as to determine the elementary charge. The experiment is easy to perform and suitable for both laboratory and demonstration using the Videoflex camera (765-1000). With the equipment, the elemental charge can be determined in 3 ways: change of charge by means of an alpha radiator, falling and rising speed with constant capacitor voltage and free voltage and falling speed without electric field.

Supplier: PHYWE

Equipment for demonstrating photoelectric power and determining Planck's constant. A photocell is equipped with filters that only transmit light of a certain wavelength. The photocell is illuminated with light from a Hg lamp. The potassium cathode then emits electrons that pass over to the unlit anode. Over time, a voltage arises that prevents new electrons from reaching the anode. The resulting voltage is measured with a measuring amplifier and a voltmeter. The measurement is repeated with filters for different wavelengths. Photocell and Hg lamp are equipped with magnets at the bottom for stable installation on the mounting plate. List of equipment.
