Question
What is the nature of electromagnetic waves?
✓

Answer

It is a three-dimensional wave which is emitted by an oscillating electric circuit in which electric field and magnetic field oscillate perpendicularly. These waves do not require any material medium for their propagation and they can travel through vacuum also. Hence, they are different from mechanical waves. They travel with maximum speed in vacuum which is equal to the speed of the light. These waves are transverse in nature and the properties of the medium remain unchanged through which they travel.
