Question

Electromagnetic waves constitute of.

Answer 1

Hint: A wave is a propagating dynamic disturbance of one or more quantities in physics, mathematics, and related fields, sometimes described by a wave equation. At least two field quantities in the wave medium are involved in physical waves.

Complete step by step solution:
EM waves are another name for electromagnetic waves. Electromagnetic radiations are made up of electromagnetic waves created when an electric field collides with a magnetic field. Electromagnetic waves can also be defined as the combination of oscillating electric and magnetic fields. Electromagnetic waves are the results of Maxwell's equations, which are the fundamental equations of physics.
A charged particle, in general, produces an electric field. This electric field exerts a force on other charged particles. Positive charges accelerate in the field's direction, while negative charges accelerate in the opposite direction of the field.
A moving charged particle creates the magnetic field. This magnetic field exerts a force on other moving particles. Because the force acting on these charges is always perpendicular to their velocity, it only affects the direction of the velocity, not the speed.
As a result, an accelerating charged particle generates the electromagnetic field. Electromagnetic waves are nothing more than electric and magnetic fields traveling at the speed of light through free space. When a charged particle oscillates around an equilibrium position, it is said to be accelerating.
Electric and magnetic fields vary sinusoidally in space and time and propagate through space in such a way that the two fields are perpendicular to the propagation direction.
Thus, Electromagnetic waves constitute oscillating magnetic and electric fields.

Note:
Electromagnetic radiations can transmit energy in a vacuum or without the use of any medium.
In communication technology, electromagnetic waves play a crucial role.
In RADARS, electromagnetic waves are used.
