Our pre-constructed Planck’s Constant Apparatus allows for a simple and cost-effective way to facilitate a good investigation into a difficult topic in modern electronics.  By monitoring the voltage at which each LED just begins to emit light, a graph of energy input as a function of light emitted frequency can be plotted and an approximate value of Planck's constant deduced.

Measure Planck’s Constant with our pre-constructed Planck's Constant Apparatus which allows for a simple and cost-effective way to facilitate a good investigation into a difficult topic in modern electronics.  

This Planck's Constant Apparatus is easy to use, compact and durable for the classroom environment. 

A series of LEDs cover the range from deep blue to infra-red. By monitoring the voltage at which each LED just begins to emit light, a graph of energy input as a function of light emitted frequency can be plotted and an approximate value of Planck's Constant deduced.  

The LEDs are mounted in a self-contained box with voltage control and monitoring points for current and voltage. A protection resistor is included to prevent damage to the LEDs. Complete with viewing tube, 5V DC power supply, and short banana plug.

Features:
  • Self-contained box with voltage control and monitoring points for current and voltage
  • Protection resistor is included to prevent damage to the LEDs
  • Viewing Tube allows for a more precise measurement of the turn-on threshold voltage
