Chapter 37, Problem 31A

What is the source of all electromagnetic waves?

To determine

To explain: the sources of electromagnetic wave.

Answer to Problem 31A

The all electromagnetic waves are generated by the electrically charged particles.

Explanation of Solution

Introduction:

The electromagnetic waves are waves of electromagnetic field.

The electromagnetic waves have both an electric and magnetic component. They are also known as EM waves. They are generated by the accelerating charged particles. The electric field associates with accelerating charge vibrate which generates the vibrating magnetic field.

For example, the oscillating charged particle has an oscillating electric field and rises to an oscillating magnetic field. The oscillating magnetic field rise to an oscillating electric field and this process continues as a propagation of the wave. The wave generated is called as EM wave.

Conclusion:

The continuous process of oscillating magnetic and electric field will generate electromagnetic waves
