China Wholesale Dual beam IR spectrophotometer Suppliers – 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
