Product Description
Different from cheap demo types for middle school, this type is a high precision/quality type for universities, it can do real calculation and test.
LCP-6A Planck's Constant Experimental System applies the photoelectric effect to measure the cur-rent-voltage (I-V) characteristic curves of a photocathode against monochromatic light at different frequencies. With the cut-off voltage shown in the curve, you can verify Einstein's equation and fur-ther confirm Planck's constant. . LCP-6A is designed for general physics experiments in higher-learning institutions to help students understand quantum nature of light and quantum theory. Through conducting the photoelectric experiment and measuring Planck's constant by means of the deceleration field method, students can learn more about this constant h, and the experimental technology and methods as well.
Experiments
1.\tMeasure I-V characteristic curve of a photoelectric tube
2.\tPlot U- curves
3.\tCalculate the follows:
a)\tPlanck's constant h
b)\tCut-off frequency ν of cathode material of a photoelectric tube
c)\tWork function Ws
d)\tVerify Einstein's equation
