Description: Planck's Constant Determination Box - Physics Experimentation Tool - Eisco Labs Apparatus designed to determine the approximate value of Plancks constant using the elbow voltage in the characteristic curves of a number of LEDsWavelengths: 470 nm, 505 nm, 570 nm, 605 nm, 655 nm, 880 nm, 940nmBox measures 8" wide, 4.75" long and 1" tall. Includes plastic viewing tube.Includes Instructional guide and experiment examplesPerfect for any classroom and useful for a variety of physics experiments This apparatus is designed to determine the approximate value of Plancks constant using the elbow voltage in the characteristic curves of a number of LEDs. There are 7 LEDs covering from deep blue at 470 nm to near IR 940 nm mounted on the box with sockets for voltage and current measurements..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 approx value of Planck's constant can be deduced. Plastic viewing tube included. Box measures 8" wide, 4.75" long and 1" tall. Required but not included: Power Supply (9V DC), Voltmeter (0-9 Volts), Ammeter (20mA) and 6 Banana Plug Connecting Leads.
