Description
Zodiac Overseas offers a precision-designed Planck’s Constant Apparatus (LED Method) for experimentally determining Planck’s Constant (h) using the photoelectric effect in LEDs. This compact setup helps students understand the quantum nature of light and energy quantization through direct voltage measurements across different colored LEDs.
Key Features:
- Study of Planck’s Constant using the threshold voltage of LEDs
- Fitted with LEDs of different wavelengths (colors) for comparative analysis
- Built-in DC regulated power supply with digital voltmeter and ammeter
- Compact and enclosed circuit with labeled test points for ease of observation
- Includes detailed manual with theory, procedure, and result calculation
- Educational and lab-friendly design with high accuracy and reliability
An essential experiment kit for physics laboratories in engineering colleges, universities, and higher secondary institutions.
