Ray Export is a leading manufacturer and supplier of Planck's Constant Experiment (By Photoelectric Effect) For High School Science Lab For High School Science Kits Lab in India,

Planck's Constant Experiment (By Photoelectric Effect) for Physics Lab- It is used for Determining of Planck's Constant and Work Function of Materials by Photoelectric Effect It was observed that most metals under influence of radiation, emit electrons. This phenomenon was termed as photoelectric emission. The apparatus comprises of the following : 1. Photo Sensitive Device : Vacuum photo tube. 2. Light source : Halogen tungsten lamp 12V/35W. 3. Colour Filters : 635nm, 570nm, 540nm, 500nm & 460nm. 4. Accelerating Voltage : Regulated Voltage Power Supply, Output : ± 15 V continuously variable through multi-turn pot Display : 3½ digit 7-segment LED Accuracy : ± 0.2% 5. Current Detecting Unit : Digital Nanoammeter It is high stability low current measuring instrument Range : 1000 mA, 100 mA, 10 mA & 1mA with 100 % over ranging facility Resolution : 1nA at 1 mA range Display : 3½ digit 7-segment LED Accuracy : ±0.2% 6. Power Requirement : 220V ± 10%, 50Hz. 7. Optical Bench : The light source can be moved along it to adjust the distance between light source and phototube scale length is 400 mm. A drawtube is provided to install colour filter, a focus lense is fixed in the back end. T
