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.

Supplier: CORNELSEN EXPERIMENTA

Insulating rod with two adjustable metal arms with ball ends.

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: 3B Scientific

Tube holder to support all S series electron tubes for easy and safe operation. The five pin sockets for the tube are concealed inside the tube holder. A cathode protection switch is integrated into the tube holder, to protect the heated cathode from excessive voltage. The base plate has a slot for attaching the Helmholtz pair of coils S.
