● More accurate measurement results by using micro current meter
● Integrated structure, easy to operate and result more accurate
● Crosstalks between spectral lines eliminated
● Background current removed
● Optimized data processing using software, more accurate results (optional).
This LEAI-51 experimental apparatus for determining Planck’s constant is used to demonstrate photoelectric effect, measure characteristic curve of photoelectric tube, verify the existence of “red limit” frquency, 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.
