PLANCK’S CONSTANT USING BLACK BODY RADIATION
Model: DT-PCBBR
A commercially available tungsten filament incandescent light bulb, high precision different coloured optical filters(Blue, Green, Yellow), Aperture / Intensity control to modulate power density incident on the detector, an AC voltage regulator to control input intensity of light bulb, Digital AC ammeter(0-2000mA) to measure current & AC voltmeter(0-200V) to measure voltage of the bulb, Selenium photocell used as photodetector duly mounted and a DC microammeter (0-20µA/0-200µA) to measure current through the photocell. Black box contains intensity control, filter holder & output detector. Complete in all respect with detailed manual and experiment video.
