Features
Introduction
This LEAI**2 experimental apparatus for determining Planck's constant is used to demonstrate the photoelectric effect, measure the characteristic curve of a photoelectric tube, verify the existence of "red limit" frequency, and calculate the Plancks constant according to the Einsteins equation of photoelectric effect. By adding optional modules of photocell, photoresistor and photodiode, current-voltage characteristics and other properties of these photoelectric devices can be measured. It is an ideal teaching apparatus for physics laboratories at colleges and universities.
