Sci-Supply Planck's Constant Apparatus, Physics Lab Device, Educational Equipment

Discover the fascinating world of quantum mechanics with Sci-Supply's Planck's Constant Apparatus. This sophisticated physics lab device is designed to demonstrate one of the most fundamental principles in quantum physics - that energy is determined by frequency rather than intensity. Perfect for educational settings, this apparatus allows students and instructors to observe and study the photoelectric effect while gaining hands-on experience with Planck's constant. The compact and user-friendly design makes it an ideal choice for physics laboratories and classroom demonstrations. This measurement kit streamlines the experimental process, helping users grasp complex quantum mechanical concepts through practical observation. Whether you're conducting advanced physics experiments or teaching foundational quantum principles, this apparatus provides reliable and consistent results while maintaining ease of operation. How It Works Light shines from a halogen tungsten lamp, passes through a selection of 5 colored filters of different wavelengths and strikes a dark box with a phototube inside. The color filters are slotted to fit the receiver and are quickly and easily changed. The frequency of light incident on the emitter of the phototube causes photoelectrons to be ejected and pass through a vacuum to a collector. The photocurrent and photo voltage are then measured by a meter.
