Determining the Planck’s constant

Omair1An interesting use of the ubiquitous light bulb is its utility in determining a fundamental constant of quantum mechanics – namely the Planck constant. The purpose of Omair qazi’s experiment was to measure Planck’s constant through the observation of black body radiation. Spectral analysis of the light was carried out verifying Planck’s radiation laws, all using filtered light from a bulb, a spectrometer and photodetectors.
