Planck's Constant with LEDs - Analysis of the experiment to estimate Planck's constant

Analysis of the results collected in the experiment to estimate Planck's constant. In video 1 threshold voltages across LEDs were measured to provide a way of measuring the amount of electrical energy used to emit photons of known wavelengths. In this video the results are analysed with the aid of a spreadsheet to estimate Planck's constant. Video 1 is available here:    • Planck's Constant - Experiment to Estimate...   You can do the analysis yourself with this worksheet to guide you through the steps: https://www.tes.com/teaching-resource... Note, this video contains some intermediate / advanced spreadsheet techniques to aid presentation of data in tables and to automate common calculations. This includes presenting data with scale factors, calculation of a gradient and y-intercept. The spreadsheet is available here: https://www.tes.com/teaching-resource... Relevant concepts: quantum physics, photons, wavelength, frequency, LEDs, electron kinetic energy.
