High school experiments
Spectral analysis. 1 setup for 1-6 students. Applicable for all age groups.
*Photoelectric effect. 2 quantitative setups for 1-4 students each, 1 qualitative setup (optional). Useful background knowledge: voltage, charged particle in electric field, frequency and intensity of light.
Millikan Experiment. 1 setup for 1-5 students. It is recommended to use the apparatus qualitatively, observing droplets in the electric field and focusing on how the experiment is designed. Useful background knowledge: voltage, charged particle in electric field, alfa particles, extrapolation.
*Electron charge to mass ratio. 2 setups, 1-4 students each. Classic Thomson Experiment. A visually pleasing experiment that ties in Northern Lighs, electrons, magnets, and circular motion. Useful background knowledge: voltage, charged particle in electric and magnetic field, circular motion, multivariable slopes for functions, magnetic field inside a coil.
Induction. 2 setups, 1-4 students each. Observing induction with an oscilloscope: how are the input and output signals of a two-coil setup connected? Useful background knowledge: induction, AC, magnetic flux, derivative.
