Description

 

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 Planck’s constant according to the Einstein’s equation of photoelectric effect. It is an ideal teaching apparatus for physics laboratories in colleges and universities.
