Definition: Electromagnetic waves or EM waves are waves that are developed as an outcome of vibrations in between an electrical field and also a magnetic area. In other words, EM waves are written of oscillating magnetic and also electric areas.Description: Electromagnetic waves are created once an electric field comes in call with a magnetic field. They are therefore known as ‘electromagnetic’ waves. The electrical field and magnetic area of an electromagnetic wave are perpendicular (at appropriate angles) to each other. They are additionally perpendicular to the direction of the EM wave. EM waves take a trip with a constant velocity of 3.00 x 108 ms-1 in vacuum. They are deflected neither by the electrical field, nor by the magnetic field. However, they are qualified of showing interference or diffractivity. An electromagnetic wave can take a trip via anything - be it air, a solid product or vacuum. It does not require a medium to propagate or take a trip from one location to another. Mechanical waves (like sound waves or water waves), on the various other hand also, require a medium to take a trip. EM waves are "transverse" waves. This means that they are measured by their amplitude (height) and also wavelength (distance in between the highest/lowest points of 2 consecutive waves). The greatest point of a wave is known as "crest", whereas the lowest point is well-known as "trough". Electromagnetic waves can be separation right into a variety of frequencies. This is known as the electromagnetic spectrum. Examples of EM waves are radio waves, microwaves, infrared waves, X-rays, gamma rays, etc.
