Description
Our Photoelectric Effect Apparatus is a precision-designed experimental setup for the determination of Planck’s Constant (h) using the photoelectric effect. This educational and research-grade instrument is widely used in physics laboratories of universities, engineering colleges, and research institutes to demonstrate one of the fundamental experiments of quantum mechanics.
The setup demonstrates how light of different wavelengths causes electron emission from a photo-sensitive surface and how the stopping potential can be measured to calculate Planck’s Constant.
