Planck's constant measurement apparatus
Measuring unit for determining Planck's constant experimentally using the photoelectric effect and investigating the laws of the photoelectric effect.
Demonstration and measuring device for quantum physics: a measuring unit for experiments with the photoelectric effect. Designed for 5 experiments: determining the Planck constant from the stopping potential for light of different wavelengths, demonstrating the laws of the photoelectric effect, plotting a photocell’s current-voltage characteristic from individual measurements at an accelerating voltage from −2 to +15 V, comparing the saturation photocurrent with different light filters and observing the current-voltage characteristic on the oscilloscope screen. Students determine a fundamental constant from their classroom measurements.
- 1.Measuring unit - 1 pc.
- Experimental determination of Planck's constant using the photoelectric effect method (measurement of the stopping potential for light of different wavelengths)
- Demonstration of the laws of the photoelectric effect: saturation photocurrent, instantaneity of the photoelectric effect, dependence of the photocurrent on the intensity of the incident light
- Recording the current-voltage characteristic of a photocell from individual measurements (accelerating voltage from −2 to +15 V)
- Comparison of saturation photocurrent when illuminating a photocell with light of different wavelengths (alternately changing filters)
- Observation of the current-voltage characteristic of a photocell on the oscilloscope screen (sawtooth sweep)
