Complete photoelectric effect experiment includes experiment files and the photoelectric effect system; complete solution designed for use with PASCO Capstone Software.
- 1x Basic Photoelectric Effect Apparatus
- 1x DC Current Amplifier
- 1x DC Power Supply I (Constant Voltage)
- 1x Cables for 850 Interface
The concept that the stopping voltage does not change with light intensity is tested using the various apertures that change the light intensity by partially blocking the light.
Use the 850 Universal Interface and PASCO Capstone to collect and analyze data.
Both the picoammeter and the power supply for the stopping voltage have sensor ports on the front that connect to the analog sensor ports of the 850 Universal Interface. PASCO Capstone automatically recognizes these instruments and can read the current and the voltage. During the experiment, each time a different filter is applied, the user clicks “Keep” in PASCO Capstone and the value of the stopping voltage for that frequency is recorded and automatically graphed vs. frequency.
- Connects to the 850 Universal Interface for data collection in PASCO Capstone
- Find Planck’s Constant to within 5%
- Verify that stopping voltage is independent of intensity
- Find characteristics of the photodiode
