Photoelectric Effect Planck's Digital Meters

The Photoelectric Effect Planck's Digital Meters device enables precise measurement of current and voltage, making it ideal for experiments related to the photoelectric effect and the study of Planck's constant in physics.

A. Lamp and Filters

The Photoelectric Effect Planck's Digital Meters include two displays: one shows the current through the Photo Tube in 0.1 nanoamps, while the other shows the backing volts required to bring the current to zero. These simultaneous readings allow for faster and less confusing experiments without the need for switching. The traditional method of using a white light source and color filters is used as the light source.

Kit Includes:

• 1 Photo-Electric Effect instrument, runs from 9V transistor battery
• 1 9V battery, type #216
• 1 Lamp as light source, 12Volt, 25 Watt, mounts on rear of unit
• 1 set of 5x Color filters, calibrated in nanometers wavelength
• 1 set 4x Apertures to set the quantity of light from the light source

Aperture orifices: 7mm, 10mm, 14mm, and 20mm diameters One test sheet and Experiment Sheets for using the instrument are included.
