A wave is described as a disturbance that carries energy through matter. An electromagnetic wave on the other hand is a wave caused by a disturbance in electric and magnetic fields. Electromagnetic waves do not require a medium in order to be transmitted. In this e-book, a summary of ideas relating to electromagnetic( light) waves are discussed.
This e-book will provide a basic understanding of electromagnetic waves. By the end, the use should understand
1. Range of frequency of each electromagnetic wave.
2. Range of Wavelengths of each electromagnetic wave.
3. How to find wave speed
4. Identify applications of electromagnetic waves
