Planck’s Constant
Planck’s ConstantThe system is an excellent illustration of modern electronics and gives a good investigation into a difficult topic in Post-16 physics.
Polarimeter
PolarimeterPolarimetry is a rewarding field of study in any Post-16 course to explore the applications of polarised light.
Polaroid Analyser
Polaroid AnalyserThe Polaroid analyser gives a convenient method for analysing polarisation of light and stress in suitable materials.
Potentiometer
PotentiometerA traditional wire potentiometer comprising 1m of 0.56mm diameter Constantan wire on a hardwood base. Connection is by 4mm sockets at either end with contact to the wire being made by a jockey at intermediate points.
