Used with electroscope 441000 for demonstrating the photoelectric effect.
If the zinc plate is illuminated with UV light from a device such as UV-C lamp item no. 287105 used with lamp holder item no. 287100, the electroscope will be discharged.
A 400 turn wire coil on one end of a wand that has two terminals at the other end to accommodate banana plug contacts, permitting easy connection of an electric circuit.
Allows students to conduct experiments to measure the speed of light. Reflect a laser off a movable mirror into a light receiver to measure phase differences.
Replacement test coupons for the Stress/Strain Apparatus.
Slides through a special slot in the Rotary Motion Sensor and allows you to measure short linear distances.
Allows a rotary motion sensor to mount on a Dynamics Track and act as a high resolution bi-directional Smart Pulley.
Allows the students observation of velocity of drop rising in an electric field, then permits calculation of the force on the charge carried by the oil drop.
The Stress Strain Apparatus lets students observe stress and strain as they stretch a material to the point of fracture.
LED Light Source with adjustable brightness control, for use with Millikan Oil Drop Apparatus.
Combines features that significantly improve the ease of setup, the durability of the Torsion Band and the quality of results. In the newer models the spheres are tungsten rather than lead.
Designed for experiments involving low light level conditions. ScienceWorkshop version.
