China Wholesale Raman Spectrometer Factories – LADP-16 Apparatus for Determining Planck’s Constant – Advanced Model – Labor
China Wholesale Raman Spectrometer Factories – LADP-16 Apparatus for Determining Planck’s Constant – Advanced Model – Labor Detail:
Planck’s Constant Experimental System applies the photoelectric effect to measure the current-voltage (I-V) characteristic curves of a photocathode against monochromatic light at different frequencies.
Experiment Examples
1. Measure I-V characteristic curve of a photoelectric tube
2. Plot U- curves
3. Calculate the follows:
a) Planck’s constant h
b) Cut-off frequency ν of cathode material of a photoelectric tube
c) Work function Ws
d) Verify Einstein’s equation
