- 1William Crookes: First Experimentcarried out experiment to investigate what happens when an electric current is passed through a glass tube containing low air pressure
- 2Cathodenegative electrodes
- 3Anodepositive
- 4outcome of experimentrays were coming from cathode and these rays cast a shadow of maltese cross, discovered cathode rays
- 5negative end of power supplyfound radiation came from metal plate inside the tube connected to negative end of power supply
- 6cathode raysinvisible to eye but when they strike glass they cause it to glow
- 7Second Experimentto investigate cathode rays properties
- 8summary of experimentplaced light paddle wheel on mounted rails in front of cathode inside tube, when current switched on the paddle rotated downward the tube
- 9conclusionsmall particles coming from cathode ray cause the wheel to rotate.
- 10properties of cathode raysthey travel in straight lines (maltese cross was sharp), cause glass to fluoresce, posses enough power to move a paddle wheel.
