Electromagnetic waves are all around us. Electromagnetic waves are a type of energy that can travel through space. They are created by the vibration of electric and magnetic fields.In this video we will analyze about electromagnetic waves.
To know more about in this topic, I recommend to read this book :
Book name : Field and Wave Electromagnetics (David K.Cheng)
