1. Chapter 26 Electromagnetism

2. Mass of Electron Determined by J.J. Thomson Determined by the deflection of the electron in a cathode ray tube

4. Electron motion in a cathode ray tube The electron travels straight if the Electric Field (E) is balanced with the Magnetic Field (B) V = E / B – V is velocity of electron – E is electric field strength Produced by charged parallel plates – B is magnetic field strength Produced by coils perpendicular to plates

5. Mass Spectrometer Used to mass charged ions (Isotopes) Used to determine the charge to mass ratios as well

7. Electromagnetic Wave A combination of a magnetic field and an electric field – Electric Field = Produced by charges (Voltages) – Magnetic Field = Produced by Orientation of Domains of positive/negatives

9. Travel at 300 million m/s

11. Radio’s Simulator
