maxwell's contributions

1. unifying theory2. prediction of em waves3. prediction of velocity

maxwell 1

linked work of orsted and faraday- created 4 laws1. charges create electric fields2. magnetic fields form closed loops3. changing magnetic fields create electric fields4. changing electric fields create magnetic fields

maxwell 2

prediction of em waves- 2 mutually propogating fields- emr can be transformed into kinetic energy- charges exposed to emr will accelerate

maxwell 3

prediction of velocity- emr moves close to the speed of light- c - f(lambda)
