Product Overview
This set provides a hands-on demonstration of the photoelectric effect, allowing students to explore the relationship between light, current, and voltage. The system uses a photocell illuminated with monochromatic light at various wavelengths, provided by a filament lamp equipped with interference filters. The digital display allows easy tracking of both the current through the photocell and the backing voltage applied to the cell.
Experiments Included:
-
Photoelectric Effect: Demonstrates how light can generate an electric current.
-
Illumination/Current Relationship: Shows how the current changes with luminous intensity.
-
Energy of a Photon: Explains how photons can drive electrons from a surface.
-
Planck’s Constant: Investigates the relationship between energy and wavelength.
-
Characteristic Curve of a Phototube: Displays the relationship between light intensity and photocurrent.
