Pendulum, Free Fall and Spring Harmonic Oscillation

Item no.: F08 Introduction By means of air resistance (also called drag), parachute helps the pilot drift to the ground slowly and safely. That is attributed to the drag counteracting free falling initiated by gravity acceleration. To meet this purpose, a comprehensive experiment kit features several characteristic are proposed: (1) experimental gravity acceleration might be

How does light oscillate?

Item no.: P1419601 Principle If the light is reflected by a glass pane it is polarised i.e. the degrees of freedom of the vibration are restricted and the wave then only vibrates in a single direction. If such polarised light falls onto a polarisation filter only allowing light through in one particular direction of vibration,

Quantum eraser

Item no.: P2220800 Principle A Mach-Zehnder-interferometer is illuminated with a laser beam. Circular interference fringes appear on the screens behind the interferometer. If polarisation filters with opposite polarisation planes are placed in the two interferometer paths the interference patterns disappear. Placing another polariser before one of the screens causes the pattern to reappear. Electromagnetic radiation
