Properties of Waves
What is a wave?
A wave is a disturbance that propagates (or travels) from the point where it was created to another point in a medium, and transfers energy from point to point but do not necessarily transfer any mass (or particle).
The following video list the common properties of waves. Content is in PDF
Electromagnetic Waves and Electromagnetic Fields
What is an electromagnetic wave?
An electromagnetic wave is a wave created as a result of the interaction of electric and magnetic fields that are oriented perpendicular to each other. Because the two fields are usually perpendicular to each other, thus, electromagnetic waves are transverse in nature.
Electromagnetic waves do not require a medium to propagate (or travel)
Electromagnetic waves are transverse waves
What are electromagnetic fields?
Electromagnetic fields are a combination of electric field and magnetic field. A moving charge always has both a magnetic field and an electric field.
A magnetic field is created around moving electric charge and magnets. While an electric field is created around electric charge.
