Photoelectric Effect System - SE-6609

SE6609_MAIN.jpg

Overview

The Photoelectric Effect System is used to perform the photoelectric experiment, determining Planck's Constant to within 5%. This apparatus uses the conventional method of determining Planck's Constant. The metal plate in the photodiode is illuminated with various frequencies of light, selected from a mercury lamp using filters. The voltage is then adjusted to stop the photoelectric  current. The stopping voltage is plotted versus the frequency and Plank's Constant is determined from the slope of the graph.

The concept that the stopping voltage does not change with light intensity is tested using the various apertures that vary the light intensity by partially blocking the light.

CAUTION: UV LIGHT; WHEN USING THIS PRODUCT, DO NOT LOOK INTO THE LAMP. UV RAYS MAY BE DAMAGING. WEAR PROPER EYE AND SKIN PROTECTION.
