Determining the gravitational constant, with the gravitation torsion balance after Cavendish- Measuring the excursion with a light pointer, Required but not included: Laser light pointer
Nexpensive, compact counter for measuring milliseconds. Each count is started and stopped by a signal at the input sockets. The device is automatically reset to zero each time it is restarted.
Photoconductivity, Multipurpose power supply. Electrical safety tested. Marked analyzer & polarizer for angle measurement. Photo current is studied as a function of the voltage applied to the photo resistor at a constant irradiance.
Geiger Counter, Versatile, easy to use and compact precision instrument for measuring alpha-, beta- and gamma-radiation. Filter selection switch at the front of the Geiger-Muller counter tube for filtering out types of radiation
