REVIEW OF ELECTROMAGNETIC WAVES

After each slide of information, there will be review questions for you to answer.

Electromagnetic waves are waves that contain an electric field and a magnetic field and carry energy.

They travel at the speed of 3.0 x 10⁸ m/s in a vacuum. This is 300,000,000 m/s.

There are seven types of electromagnetic wave which form the electromagnetic spectrum (EMS).
