Planck's Constant Apparatus
Item # P2-7135
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.

Additional Details
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
